Step-by-step reverse double crochet
To start chain 1.
Skip the first stitch, then insert your hook from front to back in the next stitch to the right.
Yarn over, pull up a loop through the stitch, yarn over, pull through 2 loops on your hook. You've created your first reverse double crochet.
Continue this all the way along your work.
If you're using this as a border and going around corners, place two reverse double crochets (rdc) into the corner stitches.
