Step 3: Add a Border
To finish off your 3D square motif blanket, add a border around the edges. Here's how:
- Attach your third color of yarn to any corner of the blanket with a slip stitch.
- Chain 1, then single crochet in the same space.
- Single crochet evenly around the entire edge of the blanket.
- When you reach a corner, single crochet 3 times in the same space to create a corner.
- Continue single crocheting around the entire edge of the blanket, working 3 single crochets in each corner.
- Join with a slip stitch to the first single crochet of the round, then fasten off and weave in ends.
