Crocheting an Infinity Granny Square

Crocheting an Infinity Granny Square

Looking for a crochet project that grows with you? The Infinity Granny Square is a beginner-friendly pattern built on simple chains and double crochets. Because you just keep adding rounds, it works up into anything from a coaster to a full throw blanket.

What You'll Need

  • Chunky Yarn
  • Crochet hook sized to match your yarn label 
  • Scissors
  • Yarn needle for weaving in ends
  • Stitch marker (optional)

The One Technique That Makes All the Difference

Before you start your first round, learn the "flip." After every completed round, flip your work over so you alternate between the right side and wrong side. This keeps your square or rectangle perfectly flat and prevents that wavy, spiraling look. You can spot the wrong side by the small horizontal bumps at the tops of the stitches. One round right side, one round wrong side. That's the whole secret.

Step 1: Start Your Center Ring

Chain 4, then slip stitch into the first chain to form a small ring. Chain 3, which counts as your first double crochet. Work 2 more double crochets into the ring. That's your first Granny Cluster (a set of 3 double crochets). Chain 2 to form a corner space, then repeat three more times until you have 4 clusters separated by four chain-2 spaces. Slip stitch into the top of the first cluster to close the round.

Step 2: Build Round 2

Flip your work. Join yarn in any corner chain-2 space. Work 3 double crochets, chain 2, and 3 more double crochets into that corner space. Move to the next corner and repeat. Continue around all four corners and slip stitch to close.

Tip: Always join new yarn in a corner space rather than a side space. It keeps the join hidden and your corners neat.

Step 3: Keep Going, Round 3 and Beyond

Flip your work again. Join yarn in any corner or side space. The rule from here is simple: at each corner, always work 3 double crochets, chain 2, 3 double crochets. On the sides, work a single Granny Cluster (3 double crochets) into every available space between the clusters of the previous round. Each new round adds one more cluster per side. Just keep repeating until the square reaches your desired size.

 

Step 4: Weave In Ends and Finish

Once your square is the size you want, cut your yarn and pull the tail through the last stitch to secure it. Thread a yarn needle and weave all loose ends neatly into the nearby stitches. Give the finished piece a light block or press if needed. Then enjoy what you made!

Final Thoughts

The Infinity Granny pattern is one of the most satisfying in crochet because it never stalls. You just keep adding rounds until it's exactly what you want. It works beautifully in ThreadArt's chunky yarn for a quick, cozy blanket, or in our cotton yarn for lighter projects like wall hangings and table toppers. Mix colors freely, keep it tonal, or use up your scraps. This pattern handles all of it with ease.
