If you’ve never made a giant granny square before, you’re in for a treat. I find them fun and relaxing to work on, and they’re the kind of project you can easily pick up and put down.

Once you get through the first few rounds and find the rhythm, this blanket becomes very easy to crochet. It also works up quickly, which makes it a great option for gifts. I hope you enjoy making this blanket as much as I have over the years!

Ch 5 and join with sl st to form a ring.

Round 1: Ch 3 (counts as dc now and throughout pattern), work 2 dc in ring, ch 2 and in ring work (3 dc, ch 2) 3 times. Join with sl st to top of ch 3.

Round 1 Notes:

  • The ch 2 forms the corners of the granny square.
  • Once the round is complete, you should have 4 dc clusters and 4 corners.

Round 2: Ch 3, 2 dc in same space. [Ch 1, in next corner space (3 dc, ch 2, 3 dc)] 3 times. Ch 1 and in starting corner (3 dc, ch 2) and sl st to top of ch 3.

Round 3 (Repeat Round): Ch 3, 2 dc in same space. [Ch 1, 3 dc in next ch 1 space, ch 1, then (3 dc, ch 2, 3 dc) in corner space] 3 times. Ch 1, 3 dc into next ch 1 space. Ch 1 and in starting corner (3 dc, ch 2) and sl st to top of ch 3.

Repeat Round 3 until your blanket reaches 40” x 40” or your desired size.

Round 3 Notes:

  • The ch 1 space is the space between the dc clusters. Each round adds more ch 1 spaces. As your blanket gets larger, you will work 3 dc into each ch 1 space.

Add a Border

Keeping the yarn attached, after completing the starting corner, ch 1 and work 2 sc in the same space, work 1 sc in each st and space around the blanket. Whenever you reach a corner space, (2 sc, ch 1, 2 sc) in the corner. Once you make your back to the starting corner, work 2 sc, ch 1, and sl st to the 1st sc. Fasten off and weave in ends.
