granny square join as you go tutorial: What Is Join-As-You-Go (JAYG)?
Join-as-you-go (JAYG) is a crochet technique where you connect motifs as you work the final round, rather than completing all motifs separately and then seaming them. Unlike traditional joining methods that require a tapestry needle and yarn tails, JAYG is worked entirely with your crochet hook.
Why Choose JAYG Over Traditional Joining?
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
| Feature | Traditional Seaming | Join-As-You-Go |
|---|---|---|
| Tools Required | Tapestry needle + yarn | Crochet hook only |
| Time to Join 49 Squares | 4–6 hours | 1.5–2.5 hours |
| Seam Visibility | Depends on method | Varies by technique |
| Project Growth | All at the end | Gradual—see progress live |
| Portability | Bulky completed squares | Work on-the-go easily |
| Error Detection | At the end (hard to fix) | As you go (easy to adjust) |
| Motivation Factor | Low (dread the seaming stage) | High (each square connects instantly) |
The granny square join as you go tutorial approach is especially valuable for large projects. When you’re making a crochet blanket with 49 or more squares, traditional seaming can feel like a second project. JAYG eliminates that barrier entirely.
Pro Tip: JAYG is perfect for traveling. Instead of carrying a bag full of completed squares, you simply work one square at a time and attach it to your growing piece. This makes it one of the most portable easy crochet projects for on-the-go crafting.
Who Should Use JAYG?
- Beginners who know the single crochet and double crochet stitches
- Intermediate crocheters looking to streamline their workflow
- Advanced makers creating complex multi-panel garments like granny square cardigans
- Anyone who has unfinished granny square projects languishing in a project bag!
Tools and Materials Needed?
The best granny square join as you go tutorial will show you multiple methods so you can choose the one that feels most natural to you.
Before starting this granny square join as you go tutorial, make sure you have the right tools. The correct hook size and yarn choice significantly affect your joining results.
Hook Selection
Use the same hook size you used to create your granny squares. Consistent hook size ensures uniform stitch height across the join. Refer to our crochet hook size chart and best crochet hooks guide for recommendations.
| Yarn Weight | Hook Size (mm) | US Size | Best For |
|---|---|---|---|
| Lace / Thread | 2.0–2.5 mm | B–0 | Doilies, fine squares |
| Sport | 3.0–3.5 mm | C–E | Wearable motifs |
| DK | 3.5–4.0 mm | E–G | Garments, bags |
| Worsted | 4.0–5.5 mm | G–I | Blankets, throws, table runners |
| Bulky | 5.5–8.0 mm | K–M | Quick projects, chunky decor |
Yarn Recommendations
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
- For blankets: Worsted weight acrylic or cotton-acrylic blend (Lion Brand Heartland, Berroco Vintage)
- For garments: DK weight merino or cotton (Scheepjes Cotton 8, Cascade 220 Superwash)
- For home decor: Cotton or cotton-blend (Lily Sugar ‘n Cream, Paintbox Cotton DK)
Using a quality crochet yarn with consistent thickness across your project ensures that joins are even and don’t pucker or gap. Check our best yarn guide for budget options.
Additional Supplies
- Stitch markers (for marking join points)
- Measuring tape (cm/inches)
- Blocking mats and pins
- Tapestry needle (for weaving in ends only—no seaming!)
- Row counter or pen and paper
What Is Method 1: Flat Slip Stitch JAYG?
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
This is the most straightforward granny square join as you go tutorial method and the one we recommend starting with. It creates a flat, nearly invisible join that works beautifully with any granny square pattern.
When to Use This Method
- Joining solid granny squares
- Projects where you want an invisible seam
- Blankets, scarves, and shawls
Step-by-Step Instructions
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
Step 1: Prepare Your First Square
Complete all rounds of your first granny square through the final round. Do not fasten off—leave the yarn attached. This square becomes your “base” square. If your granny square pattern specifies 4 rounds, work all 4 rounds and stop at the corner.
Step 2: Position the Second Square
Complete all rounds of your second square EXCEPT the final round. Stop when you’ve completed the penultimate round. Place the second square adjacent to the first, right sides facing up, with the edge you want to join aligned.
Step 3: Begin the Joining Round
Working on the second square, begin the final round. When you reach a chain space that corresponds to a chain space on the completed square:
- Work your first stitch (e.g., 3 dc) into the chain space of the second square
- Insert your hook into the corresponding chain space of the first square
- Yarn over and pull through
- Complete the stitch on the second square as normal
- Continue working around the second square, joining at each chain space along the shared edge
Step 4: Continue Around
When you reach the next corner of the second square, work the corner as normal (3 dc, ch 2, 3 dc). Continue around the remaining unjoined edges. No joining needed on these sides.
Step 5: Add Subsequent Squares
For the third square, you’ll join to either the first or second square (or both, if it’s a corner square joining two edges). The process is identical: work to the chain space to be joined, insert hook into the adjacent square’s chain space, pull through, and complete.
Pro Tip: Always join at chain spaces, not in the middle of stitch groups. This ensures the join falls at the natural “seam” points and maintains the square’s shape. If you’re experiencing tension issues, our guide on fixing crochet tension can help.
Stitch Count Reference for Standard Squares
| Square Size | Sides | Chain Spaces Per Side | Stitches Per Side |
|---|---|---|---|
| 3-round square | 4 | 2 | 6 dc + 1 corner |
| 4-round square | 4 | 3 | 9 dc + 1 corner |
| 5-round square | 4 | 4 | 12 dc + 1 corner |
| 6-round square | 4 | 5 | 15 dc + 1 corner |
What Is Method 2: Chain-Loop JAYG?
The best granny square join as you go tutorial will show you multiple methods so you can choose the one that feels most natural to you.
The chain-loop method creates a decorative, lacy join with visible chain loops between squares. It’s ideal for openwork designs and projects where the join itself is part of the aesthetic.
Best Uses
- Lightweight summer blankets
- Crochet tops and dresses where drape is important
- Projects using filet or lace-style squares
Step-by-Step Instructions
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
Step 1: Work the Final Round with Chain Spaces
On the second square’s final round, when you reach the shared edge, work your stitch group (e.g., 3 dc), then chain 3 instead of chaining 1 between groups.
Step 2: Create the Joining Loop
Insert your hook into the corresponding chain space on the adjacent square. Slip stitch to join. Chain 3 again, then work your next stitch group on the current square.
Step 3: Repeat
Continue this pattern—3 dc, ch 3, sl st to adjacent square, ch 3—along the entire shared edge. The chain-3 loops create a decorative bridge between squares.
Pro Tip: Adjust the chain length to control the spacing between squares. Chain-2 creates a tighter join (good for dense fabrics), while chain-4 creates a more open, airy join. For a crochet cardigan, use a shorter chain to prevent gaps that could catch on things.
Measurements
Chain-2 join: Adds approximately 0.5 cm (0.2 in) of space between squares
Chain-3 join: Adds approximately 0.8 cm (0.3 in) of space between squares
Chain-4 join: Adds approximately 1.2 cm (0.5 in) of space between squares
What Is Method 3: Single Crochet JAYG?
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
The single crochet JAYG creates a sturdy, structural join. It’s the most secure method and is ideal for projects that will see heavy use.
Best Uses
- Market bags and tote bags
- Baskets and storage items
- Dishcloths and utility items
- Children’s blankets (durable and washable)
Step-by-Step Instructions
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
Step 1: Position Squares
Place squares right sides together or right sides facing up (depending on desired look).
Step 2: Work Through Both Layers
When reaching the edge to be joined, insert your hook through both the current square and the adjacent square. Work a single crochet through both layers. Continue this for each stitch along the shared edge.
Step 3: Corner Treatment
At corners, work 3 single crochets into the corner chain space of both squares. This creates a reinforced corner that won’t pull apart.
Pro Tip: The single crochet join adds a visible ridge between squares. If this bothers you, work the join with a contrasting color yarn and treat it as a design element. This works especially well with colorful geometric designs.
What Is Method 4: Double Crochet Join JAYG?
This method uses double crochet stitches to create a raised decorative join between squares. It’s the most visible JAYG method but also the most decorative.
Step-by-Step Instructions
The best granny square join as you go tutorial will show you multiple methods so you can choose the one that feels most natural to you.
Step 1: Work to the Join Point
On the second square’s final round, work your stitch group, chain 2.
Step 2: Double Crochet Join
Instead of a slip stitch, work 1 or 2 double crochet stitches into the adjacent square’s chain space. Then chain 2 and continue on the current square.
Step 3: Continue Around
Repeat this pattern along the entire shared edge. The double crochet “bridge” between squares creates a raised, dimensional join.
When to Use This Method
- Decorative blankets where the join is a feature
- Chunky yarn projects where a bold join looks intentional
- Geometric designs that benefit from defined grid lines

What Is Method 5: Invisible JAYG?
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
The invisible JAYG is the gold standard for clean, professional-looking joins. It creates a join that is virtually undetectable on the right side of the work. This is the most advanced method in our granny square join as you go tutorial, but the result is worth the extra effort.
Step-by-Step Instructions
Step 1: Identify Join Points
On the completed (adjacent) square, identify the top loops of the stitches along the edge to be joined. You’ll be working into the front loop only (FLO) of these stitches.
Step 2: Work the Joining Stitch
On the second square, when you reach a chain space to be joined, work your stitch group as normal. Then insert your hook under the front loop only of the corresponding stitch on the adjacent square. Complete a slip stitch. This creates a nearly invisible connection.
Step 3: Corner Join
At corners, work the corner stitch group on the current square, then join to the adjacent corner with a slip stitch through the front loop only. This keeps corners aligned perfectly.
Pro Tip: The invisible join works best with squares that have been blocked to the same size. If your squares vary even slightly, the join will show uneven tension. Block first, then join. See our guide on granny square sizing for blocking tips.
What Is Planning Your Layout?
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
Before you begin joining, plan your layout. This is a critical step that many crafters skip, leading to disappointing results. The granny square join as you go tutorial process works best with a clear plan.
Layout Methods
Random Scatter Layout
Lay out all completed squares in a random but aesthetically pleasing arrangement. Take a photo for reference. This works well for scrap-buster projects using the free crochet patterns approach.
Color Gradient Layout
Arrange squares from light to dark or following a color wheel progression. This creates a gorgeous ombre effect in the finished piece.
Geometric Pattern Layout
Arrange squares to create a secondary pattern—diagonals, diamonds, or pinwheels. This works best when each square uses 2–3 colors consistently.
How to Plan a 7 × 7 Blanket (49 Squares)
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
- Make all 49 squares first (complete through the penultimate round for JAYG)
- Block all squares to exactly the same measurements (e.g., 12.5 cm / 5 in each)
- Lay out on the floor or a design board, arranging colors to your satisfaction
- Number each square with a stitch marker or safety pin, noting row and column
- Photograph the layout from directly above for reference
- Begin joining row by row, starting with the first complete square (no joining on its final round)
Pro Tip: When using JAYG, you typically work in rows or columns. Complete one full row, then join the next row to it. Working in strips is generally easier than working in concentric rings for rectangular projects. For a baby blanket (typically 90 × 120 cm), you might work 7 rows of 8 squares each.
What Is Comparison of JAYG Methods?
Choosing the right joining method depends on your project type and aesthetic goals. Here’s a comprehensive comparison to help you decide:
| Method | Difficulty | Visibility | Strength | Speed | Best Project Type |
|---|---|---|---|---|---|
| Flat Slip Stitch | Easy | Very Low | Medium | Fast | Blankets, throws |
| Chain-Loop | Easy | High (decorative) | Low–Medium | Fast | Summer tops, lace items |
| Single Crochet | Easy | Medium (ridge) | Very High | Medium | Bags, baskets, kids’ items |
| Double Crochet Join | Medium | Very High | High | Medium | Decorative blankets |
| Invisible | Advanced | Nearly None | Medium–High | Slow | Garments, fine blankets |

Even experienced crocheters run into issues with JAYG. Here are the most common problems and their solutions in this granny square join as you go tutorial:
Mistake 1: Puckering Along the Join
Cause: Your joining stitches are tighter than your regular stitches.
Fix: Use a slightly larger hook (0.5 mm bigger) for the joining round only, or consciously loosen your tension on joining stitches. Our article on crochet tension has detailed exercises for improving consistency.
Mistake 2: Gaps Between Squares
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
Cause: Your joining stitches are too loose, or you’re skipping chain spaces.
Fix: Count your chain spaces on each side before joining. A standard 4-round granny square has 3 chain spaces per side (plus 1 corner space). Make sure you’re joining at every chain space.
Mistake 3: Misaligned Corners
Cause: Squares are different sizes or corner stitch counts don’t match.
Fix: Block all squares to identical measurements before joining. If using a solid granny square pattern, ensure each corner has the same number of stitches. Read our crooked granny square guide for alignment tips.
Mistake 4: Twisted Join
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
Cause: You accidentally joined the wrong edge of the adjacent square, or the square rotated during joining.
Fix: Always place squares on a flat surface and verify orientation before joining. Use stitch markers to pin squares in position if needed.
Mistake 5: Visible Yarn Carries
Cause: When joining multiple edges of a single square, the carried yarn shows on the front.
Fix: When a square joins to two adjacent squares, work the yarn carries along the wrong side. Or, fasten off after joining the first edge and rejoin for the second edge. This creates more ends to weave but produces a cleaner look.
Pro Tip: If you’re joining a square to two edges (a corner position), always join the horizontal edge first, then the vertical edge. This prevents the work from twisting and keeps your edges straight. For garments like a granny square cardigan, this systematic approach is essential.
What Is Advanced Layout Techniques?
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
Once you’ve mastered the basic JAYG methods, try these advanced layouts:
Diagonal Join Layout
Instead of working in straight rows, join squares diagonally from corner to corner. This creates a gorgeous diamond-patterned blanket. Start at one corner, join 1 square, then 2, then 3, building a triangle shape, then decrease back down. This technique works beautifully for shawl and poncho shapes.
Mixed-Size Layout
The best granny square join as you go tutorial will show you multiple methods so you can choose the one that feels most natural to you.
Combine different sized squares for an organic, freeform look. Use one 20 cm (8 in) center square surrounded by twelve 10 cm (4 in) squares, then fill gaps with smaller 5 cm (2 in) squares. This creates a gorgeous medallion-style blanket.
Color Block Strips
Join squares in vertical strips, each strip a different color family. This creates a striped blanket effect where each “stripe” is made of individual granny squares. It’s a modern take that looks incredible with crop top projects too.
What Is Border and Finishing?
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
After joining all your squares, add a border to frame the piece and hide any uneven edges. The border also helps “lock” the join in place and gives the project a polished finish.
Simple Border (1 Round)
Work 1 round of single crochet around the entire perimeter, working 3 sc in each corner. This provides a clean, minimal edge. For a 7 × 7 square blanket (approximately 87.5 × 87.5 cm / 34.5 × 34.5 in), you’ll need approximately 350 stitches total for the border round.
Decorative Border (3 Rounds)
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
- Round 1: Single crochet evenly around (3 sc in each corner)
- Round 2: *Double crochet in next stitch, chain 1, skip 1*. Repeat around. This creates a lacy foundation.
- Round 3: In each chain-1 space, work (dc, ch 2, dc). In each skipped sc, work 1 sc. This creates a pointed shell border.
Granny Stripe Border
Work 2–3 rounds of traditional granny clusters (3 dc groups) around the perimeter. This echoes the square design and provides visual continuity. Work 3 dc, ch 2, 3 dc in each corner. For a 10-round square blanket, this border adds approximately 2.5 cm (1 in) to each side.
Pro Tip: Always block your completed, joined piece before adding the border. Blocking ensures the edges are straight and the corners are true 90-degree angles. Then work the border on the blocked piece for the most professional result. For blocking guidance, see our crochet tips collection.
Frequently Asked Questions
Once you master the granny square join as you go tutorial techniques, you will never go back to traditional seaming methods again.
Is join-as-you-go harder than traditional seaming?
Not at all. In fact, many crocheters find it easier because you’re using your hook—a familiar tool—instead of a tapestry needle. The basic flat slip stitch method in this granny square join as you go tutorial uses only stitches you likely already know: chain, double crochet, and slip stitch. The learning curve is gentle, especially if you’re comfortable with the foundational crochet stitches.
Can I use JAYG with any granny square pattern?
The best granny square join as you go tutorial will show you multiple methods so you can choose the one that feels most natural to you.
Yes, with a small modification. Complete all rounds of each square except the final round. Then use the JAYG method to work the final round while joining. This works with traditional granny square patterns, solid granny squares, and even motif-based designs like flower patterns.
Why is my JAYG join puckering?
Puckering usually means your joining tension is too tight. Try these solutions: (1) Go up 0.5 mm in hook size for the joining round, (2) Consciously work the joining stitches slightly looser, (3) Make sure both squares are the same size before joining—block them if necessary. Read more about tension issues in our tension guide.
How do I join the last square in a row?
Following a granny square join as you go tutorial saves hours compared to sewing individual squares together after completing them all.
The last square in a row needs to join to two edges: the previous square in the same row, and the square in the row above. Work the first edge join, continue around, then work the second edge join when you reach it. You’ll need to carry your yarn along the wrong side or fasten off and rejoin for the second edge.
Can I use JAYG for non-square motifs?
Absolutely. JAYG works with hexagons, triangles, circles, and any motif with a final round that can be adapted. The technique is the same—work the final round while joining at corresponding points on the adjacent motif. This is especially useful for projects like vests or dresses where hexagon motifs create flattering geometric patterns.
For more joining techniques, visit Ravelry join-as-you-go discussion and Spruce Crafts joining methods guide.
How many ends do I need to weave in with JAYG?
A granny square join as you go tutorial is essential for any crocheter who hates the tedious seaming process at the end of a project.
Significantly fewer than traditional joining. You’ll have one starting tail and one ending tail per square (2 per square). For 49 squares, that’s 98 ends—compared to traditional seaming which adds a long joining yarn tail for each seam. Using the same color for joining as the final round of your squares allows you to carry yarn and reduce ends even further. Check our abbreviations guide if you need help reading pattern instructions for efficient yarn management.
Now that you have all five methods at your fingertips, pick up your hook and start joining! The granny square join as you go tutorial approach will transform those stacks of completed squares into finished projects faster than you ever imagined.
