Ten free Halloween granny squares, from a pumpkin and a ghost to a bat, a black cat, an eyeball and a skull. Some are a single crocheted square and others are an applique sewn onto a plain square, so check each page before you choose yarn.
A granny square is a small project, which makes it easy to try a few. Several of these designers suggest turning them into blankets, bags or cushions. If you want more of one motif, I have roundups for ghosts and spiders, a guide to granny squares in general, and my own devil eye granny square tutorial.
Halloween granny squares to explore
1. Crochet Pumpkin Granny Square
Designer Sarah Zimmerman at Repeat Crafter Me. The written pattern is the free Red Heart Pumpkin Patch Blanket on Yarnspirations, which includes the pumpkin square and how to join the squares into a blanket. Sarah used Red Heart Super Saver in Pumpkin, Spring Green and Cafe Latte, and she made a video that walks through the whole square. Yarnspirations rates the pattern easy.

2. Boho Crochet Ghost Granny Square
Designer Kimberly at Single Girl’s DIY. A ghost square that starts from a magic ring in white and uses beginner stitches. Kimberly suggests a small 2.3 mm hook and calls black and white the classic colors, though orange, bright purple, neon green or glow in the dark yarn also work. An ad free PDF is available for $3 if you would rather print it.

3. Spider Web Granny Square
Pattern from Granny Square.Me. A spider web worked in one color, about 3.74 by 3.74 inches with a 3 mm hook and any yarn you like. The page calls it beginner friendly, uses only basic stitches and gives step by step photos for all seven rounds. Soft gray looks like a real web, and black or glow in the dark yarn gives a darker Halloween look.

4. Bat Granny Square
Designer Kimberly Arenas at The Caffeinated Snail. A bat on a moon background, roughly 7 inches on each side, worked in worsted weight acrylic with a 5.5 mm hook. Everything except the big moon is a separate applique sewn on, so you can place the pieces where you like. Kimberly used black, purple, cornmeal and lilac, and you can change the size with a different hook or yarn.

5. Black Cat Granny Square
Pattern from GoldenLucyCrafts. A black cat face on a granny square, about 5.75 inches across and rated intermediate. You crochet the square, two eyes and a nose, sew the face pieces on and embroider the mouth and whiskers. It calls for medium weight yarn in black, white and orange with a 5 mm hook, and it also lists light weight cotton and a 2.75 mm hook. An ad free PDF is sold on Etsy.

6. Halloween Eyeball Granny Square
Designer Fay at Stitch by Fay. An eyeball square in DK yarn (black, white, red and a color of your choice for the iris) with a 3 mm hook, about 4.75 by 4.75 inches. Fay shows how to change colors in half double crochet and uses a stacked single crochet instead of a starting chain on the last two rounds. She suggests one square as a mini trick or treat bag, or several for a cushion or tote.

7. Skull Granny Square
Pattern from Granny Square.Me. A skull square about 3.15 inches across, worked in two high contrast colors with a 3 mm hook. The page calls the basic version good for beginners and includes a video. The same site has solid, triangle, crown and flower skull versions if you want to mix them in one project.

8. Halloween Frankenstein Granny Square
Designer Maria Weaber at Maria’s Blue Crayon. A Frankenstein applique sewn onto a gray granny square, from week 4 of her Halloween Blanket Crochet Along. The applique uses green and black yarn, a 4 mm hook and two 6 mm safety eyes, with the mouth and scar stitched on in black. A video walks through it, and Maria calls it quick to make.

9. Halloween Witch Granny Square
Designer Maria Weaber at Maria’s Blue Crayon. The witch comes from week 2 of the same crochet along, sewn onto a gray square with purple squares in the set. Maria says it is the most labor intensive of the series, though not hard. It uses green, purple, black and orange yarn, a 4 mm hook, 6 mm safety eyes and a loop stitch, and a video is included.

10. Halloween Candy Corn Granny Square
Designer Maria Weaber at Maria’s Blue Crayon. A candy corn applique worked in rows of half double crochet, changing from yellow to orange to white, then sewn onto a gray square. The applique uses a 4 mm hook and the granny square uses a 6 mm hook. Maria says the color changes are very easy, and she pairs it with orange squares in the blanket.
