These granny square afghan patterns all grow from a single continuous square rather than requiring a full grid of separate motifs. Their stated yarn weights and blanket sizes make it easier to choose a starting point for a baby blanket or larger square afghan.
Granny square afghan patterns to explore
These grow as one continuous piece rather than separate motifs, but stitch markers still help track your round count on the larger sizes.
1. Granny Square Blanket
Sarah-Jayne Fragola at Bella Coco Crochet builds the blanket as one continuous giant granny square. The listed baby blanket finishes at 27 inches square with a shell border. Because the whole blanket is one motif, there’s no seaming or joining round at all, just the shell border to finish once you reach your target size.
2. Continuous Granny Square Blanket
Jo at Jo to the World Creations repeats the main granny-square round to enlarge the blanket. With size-3 yarn, the pattern’s blanket with border measures approximately 30 inches square. Repeating a single round formula keeps the pattern simple to follow even as the square grows well past baby-blanket size.
3. How to Crochet a Granny Square Blanket
Lauren Brown’s continuous granny square blanket sample measures about 29 by 29 inches. Because the construction grows by rounds, you can alter the finished size by adding or removing rounds rather than recalculating a grid of separate squares. View the pattern.
4. Blushing Blooms Granny Square Afghan
Shehnaaz joins 20 oversized four-round starburst-inspired squares into five strips, then adds a two-round single-crochet and half-double-crochet border. Super-chunky chenille creates a 34 by 41-inch finished afghan, with an optional paid PDF offered separately. View the pattern.
5. Color-Changing Granny Square Throw
Carolyn Calderon’s easy US-terms throw uses 50 color-changing classic granny squares measuring 6.5 inches each. The free post includes the square rounds, a join-as-you-go fifth round, an assembly chart, and a three-round edging. The finished blanket measures 34.5 by 67 inches. View the pattern.
6. One Big Granny Square Blanket
Sonya Blackstone’s free “One Big Granny Square Blanket” grows center-out as one continuous square rather than joining separate motifs, in worsted-weight yarn on an H/8, 5mm hook. The sample finishes about 30 by 30 inches, and the round-repeat formula lets you keep going for a larger throw. View the pattern.
7. Continuous Crochet Granny Square Pattern
Fay at Stitch by Fay works this continuous square in worsted-weight yarn on a 6mm hook, using a stacking single crochet instead of a starting chain at the top of each round and turning the work every round to keep the corners square instead of spiraling. View the pattern.
