Ever wonder how to fill in those ch-2 corners? Here’s a special stitch that closes gaps usually created by the ch-2 corner. Don’t let the odd stitch overwhelm you.

This tutorial uses double crochet, but you can use the same technique for half double or single crochet also. Just replace ‘dc’ in the directions with the crochet stitch of your choice..
