32 Crochet Granny Square Project Ideas You’ll Want to Make
Granny squares never really go out of style. They’re portable, forgiving, and endlessly customizable. Once you know the basic square, a whole world of projects opens up.
Whether you’re new to crochet or you’ve got a hook callus already, this list will keep you busy for a long time. Grab your yarn stash and let’s get into it.
1. Classic Granny Square Throw Blanket
You’ll need worsted weight yarn in five or six colors, a 5mm hook, and a yarn needle for weaving ends. Each square starts with a magic ring, then rounds 1 through 4 build the classic three double crochet cluster pattern with chain 2 corners. Most throws use 48 to 64 squares depending on size.
Join your squares in rows of six or eight using a flat slip stitch seam. This keeps the blanket from feeling bulky. Finish with two or three rounds of single crochet around the whole edge to hold everything together.
Weave in ends as you go rather than saving them for the end. It saves you hours later and keeps the back looking tidy.
2. Crochet Granny Square Tote Bag
Cotton yarn works best here since it holds shape better than acrylic. Use a 4mm or 5mm hook and make nine four inch squares, three rounds each. Join them into a three by three grid to form the bag panel, then make a second matching panel.
Seam the two panels together along the sides and bottom, leaving the top open. Add a cotton or canvas lining by hand stitching it inside, which stops the granny squares from stretching under weight. For the handles, crochet two chains of about 60 stitches, then single crochet three rows to thicken them before attaching.
A row of single crochet around the top opening gives the bag a clean, finished edge.
3. Granny Square Cardigan
This is an intermediate project. You’ll need worsted weight yarn, roughly 800 to 1200 yards depending on size, and a 5mm hook. Squares are made to a consistent four or five inch size, then arranged flat before joining, since layout really matters for how the color pattern reads across the front.
You’ll need two back panels or one full back panel, two front panels, and two sleeve panels, each built from rows of joined squares. Join panels using a whip stitch or slip stitch seam, then set in the sleeves last. Add a single crochet border around the neckline, cuffs, and hem to keep edges from curling.
Try the whole thing on before your final border round. It’s much easier to adjust length now than after everything is joined.
4. Colorful Granny Square Cushion Cover
Make four matching squares, five inches each, using worsted weight yarn and a 5mm hook, three or four rounds per square depending on desired size. Join two squares per side, then join the sides to form a square pillow front.
For the back, either crochet four more matching squares or work a solid single crochet panel the same finished size, which is faster and hides seams less. Join front and back around three sides, insert your pillow form, then whip stitch the last side closed.
A shell stitch or picot border around the whole cover adds a nice decorative touch without much extra effort.
5. Crochet Granny Square Bucket Hat
Use stretchy cotton or cotton blend yarn with a 4mm hook. Make six to eight slightly smaller squares, about three inches, worked in half square triangles rather than full squares. This lets them curve naturally around the head shape instead of sitting flat.
Join the half squares into a ring for the crown, then work the brim separately as a flat round piece increasing every row to flare outward. Seam the brim to the crown edge, matching centers evenly.
Block the hat over a bowl while damp. It helps the shape hold once it dries.
6. Granny Square Table Runner
Grab worsted weight cotton yarn in two or three coordinating colors and a 5mm hook. Make five or six squares, four rounds each, then join them in a single straight line along one edge only.
Once joined, work two rounds of single crochet around the entire runner in your main color. This straightens out any uneven seams and gives it a finished look. A third round in a contrast color adds a nice pop against the table.
Keep tension even across all your squares. Table runners show unevenness more than blankets since there’s nothing to distract the eye.
7. Crochet Granny Square Baby Blanket
Soft acrylic or a cotton acrylic blend is kindest on baby skin. Use a 4mm hook and keep squares small, around four inches, three rounds each, in pastel or gender neutral colors. Most baby blankets use 30 to 42 squares.
Join in a flat grid using a join as you go method, which avoids a big seaming session at the end. Finish with a shell stitch border, worked in one round of shells into every other stitch around the edge.
Wash your yarn choice before starting if you’re unsure about softness. Some acrylics soften more after a first wash.
8. Granny Square Crossbody Bag
Use a 4mm hook and worsted cotton yarn. Nine small squares, three inches each, three rounds, join into a three by three rectangle for the bag body. Fold the rectangle in half and seam the two sides, same as the tote method but smaller.
Line the inside with fabric for structure, since a small bag holds shape better with backing. For the strap, chain around 120 stitches for a crossbody length, then single crochet two rows back across to reinforce it.
Add a button or drawstring closure at the top so things don’t fall out on the move.
9. Crochet Granny Square Sweater Vest
You’ll need about 600 yards of worsted yarn and a 5mm hook. Build front and back panels from joined squares, four to five inches each, sized to your bust and length measurements. No sleeves needed, which makes this a great next step after a blanket.
Join panels at the shoulders and sides, leaving arm openings unsewn. Single crochet around the armholes, neckline, and hem in one matching color to unify the whole piece.
This is a forgiving project for using up mismatched squares from other projects, since a vest reads as intentionally scrappy.
10. Granny Square Market Bag
Cotton yarn is a must here for strength. Use a 5mm hook and twelve squares, four inches, joined in a three by four grid for extra room. Fold and seam like the tote, leaving the top fully open.
Instead of a lining, market bags work well left open weave, which makes them lighter for produce and groceries. Add two sturdy straps using double crochet rows instead of chains, since they’ll carry more weight.
Reinforce the strap attachment points with a few extra stitches. This is where market bags tend to wear out first.
11. Crochet Granny Square Scarf
Use worsted yarn and a 5mm hook. Make eight to ten squares, four inches each, and join them in a single long row rather than a grid. This creates a scarf shape naturally.
Add fringe along both short ends by cutting yarn strands and knotting them through the corner stitches. A single round of single crochet along both long edges keeps things from curling.
This is a great scrap yarn project since a scarf doesn’t need matching squares, just a pleasing color flow.
12. Granny Square Coasters Set
Small and quick. Use cotton yarn, a 4mm hook, and make squares around three inches, two or three rounds only. Cotton is important here since coasters deal with condensation and heat.
Make four or six to match a full table setting. No joining needed, these work as individual pieces. Add a single round of single crochet around the edge for a cleaner finish and slightly sturdier hold.
Block each coaster flat while damp so they sit evenly on a table.
13. Crochet Granny Square Wall Hanging
Use worsted yarn in a color palette that fits your space, and a 5mm hook. Join nine to sixteen squares into a large rectangle or square shape, same joining method as the blanket but on a smaller scale.
Instead of a border, add a wooden dowel across the top by folding the top edge over the dowel and stitching it in place. Attach yarn or twine to both ends of the dowel for hanging.
Fringe along the bottom edge gives it a more finished, tapestry style look.
14. Granny Square Plant Pot Cover
Use cotton yarn and a 4mm hook. Work squares slightly larger than your pot’s diameter, then join four squares around a central point to form a cylinder shape, seaming the sides together.
Leave the bottom open so the pot’s drainage isn’t blocked, or add a solid crocheted base if you want a fully enclosed cover. A drawstring at the top lets you cinch it around varying pot sizes.
This is a fast one afternoon project and a great way to use up leftover squares from bigger projects.
15. Crochet Granny Square Laptop Sleeve
Use sturdy cotton yarn and a 4mm hook for a tighter, protective fabric. Make squares sized to your laptop’s dimensions, join them into two matching panels for front and back.
Seam three sides together, leaving the top open for sliding the laptop in. Add a flap or button closure at the top for extra protection. A layer of felt or fabric lining adds cushioning between the crochet and your device.
Check your gauge carefully here. A looser fabric won’t protect the laptop as well as a snug, tight stitch.
16. Granny Square Patchwork Jacket
This is a bigger commitment, closer to 1000 to 1500 yards of yarn. Use a 5mm hook and build oversized panels from mixed size squares for a patchwork look rather than uniform ones.
Assemble front panels, a back panel, and sleeves the same way as the cardigan, but leave the jacket unstructured and open at the front instead of adding buttons. A single crochet border unifies all the mismatched pieces.
This is the ultimate stash buster project if you’ve been collecting leftover squares for a while.
17. Crochet Granny Square Beach Bag
Use cotton yarn and a 5mm hook for durability against sand and sun. Twelve squares, four inches, joined into a rectangle, folded and seamed like the tote and market bag.
Beach bags benefit from a drawstring or zipper top since they’re often tossed around. Add a fabric lining for extra strength if you’re carrying towels and sunscreen. Long single crochet strap rows handle heavier beach loads better than chains.
Bright, bold color combinations work especially well for this one.
18. Granny Square Headband
A quick project using leftover yarn. Use a 4mm hook and make two or three small squares, two rounds each. Join them in a short row to fit around the head.
Add a button and loop closure, or make it stretchy with an elastic band sewn to the back for a no fuss fit. This is a great project for teaching kids the basics of joining squares.
19. Crochet Granny Square Skirt
Use worsted or DK weight yarn and a 4mm or 5mm hook. Build a front panel and back panel from joined squares sized to hip and length measurements, then seam the sides leaving room for a waistband.
Add an elastic waistband by folding over the top edge and single crocheting a channel, then threading elastic through. A hem border in single crochet finishes the bottom cleanly.
This project works best with squares in a consistent size so the drape stays even all the way around.
20. Granny Square Christmas Stocking
Use worsted yarn in festive colors and a 5mm hook. Make four to six squares, join into a rectangle, then fold and seam into a stocking shape, curving the toe seam slightly for shape.
Add a cuff at the top using a few rows of single crochet in a contrast color, and a hanging loop made from a short chain. Personalize with a name in duplicate stitch or a small crocheted tag.
21. Crochet Granny Square Pillow Sham
Similar build to the cushion cover but with an envelope back instead of a sewn seam. Make four squares for the front, join, and single crochet a border. For the back, work two overlapping rectangular panels instead of a sewn opening.
This lets you remove the pillow form easily for washing. Add buttons along the overlap for a more polished, sham style closure.
22. Granny Square Apron
Use cotton yarn and a 4mm or 5mm hook. Join squares into a rectangle sized for the apron front, then add straps and ties using long chains reinforced with a row of single crochet.
A pocket can be added by crocheting one extra small square and attaching it to the front panel on three sides. Cotton yarn holds up much better here since aprons see regular washing.
23. Crochet Granny Square Placemats
Use cotton yarn and a 5mm hook. Join four squares per placemat into a two by two grid, then add one or two rounds of single crochet around the edge for structure.
Make a set of four or six to match your table runner or coasters. Keep tension consistent across the set so all placemats lay flat and match in size.
24. Granny Square Picnic Blanket
Use worsted or heavier weight cotton blend yarn for durability outdoors, with a 5mm or 6mm hook. This blanket needs more squares than a throw, usually 80 or more, since picnic blankets are typically larger.
Join in a sturdy flat grid, and consider a canvas or waterproof backing sewn on for outdoor use. A thick single crochet border adds extra durability at the edges where wear happens most.
25. Crochet Granny Square Phone Pouch
A fast, beginner friendly project. Use cotton yarn and a 4mm hook, make two small matching squares sized to your phone, two or three rounds each.
Seam three sides together, leaving the top open. Add a chain strap for a crossbody style pouch, and a button closure at the top to keep your phone secure.
26. Granny Square Hot Pad or Trivet
Use cotton yarn only, since it handles heat safely, and a 4mm hook. Make one or two squares per trivet, three to four rounds, and consider doubling the yarn or working two layers together for extra thickness and heat protection.
A hanging loop at one corner makes it easy to store near the stove.
27. Crochet Granny Square Maxi Dress
An ambitious project needing 1200 plus yards of yarn and a 5mm hook. Build front and back panels from joined squares sized to bust, waist, and hip measurements, with panels widening toward the hem for a maxi length flare.
Seam the sides, add straps or sleeves depending on your design, and finish the neckline and hem with single crochet borders. Try the dress on at multiple stages, since fit matters more here than in almost any other project on this list.
28. Granny Square Christmas Tree Skirt
Use worsted yarn and a 5mm hook. Join eight to ten squares in a circular arrangement around a center point, or join them into a large flat circle shape using triangle segments between squares to fill the gaps.
Leave a straight cut line from center to edge, plus a small circle cut out at the center, so it can wrap around the tree base. Add ties at the opening to hold it closed.
29. Crochet Granny Square Storage Basket
Use sturdy cotton yarn or cotton blended with a bit of rope or T-shirt yarn for structure, and a 6mm hook. Join four squares for the base, then work the sides upward using rows of double crochet worked directly into the base squares.
A single crochet round at the top rim helps the basket hold its shape and not flop over when empty.
30. Granny Square Pet Bed Cover
Use durable, washable cotton or acrylic yarn and a 5mm hook. Join squares into a rectangle sized to fit over your pet bed cushion, then add a zipper or envelope back opening for easy washing.
This is a great practical project since pet bed covers get dirty fast and having a removable, washable cover saves the cushion underneath.
31. Crochet Granny Square Shawl Wrap
Use a lighter DK or worsted weight yarn and a 4mm hook for drape. Join squares in a triangular or rectangular arrangement, increasing square count toward the center back for a classic shawl shape.
A shell stitch or picot border around the outer edges adds movement and a soft finished look. This is a lovely project for using variegated or gradient yarn.
32. Granny Square Scrap Yarn Basket
The ultimate stash buster to end the list. Use whatever cotton or acrylic scraps you have and a 5mm hook. Join mismatched squares into a base, then build up the sides with rows of double crochet, just like the storage basket.
Since it’s fully scrappy, there’s no need to match colors or yarn weights carefully. This is the perfect last project to clear out those small leftover balls before starting something new.
