This is my favorite stitch. It adds good height, so when making an afghan, if this stitch is used the most, it seems to go faster for me. So, lets start with the chain...to give height to the edge of the DC (double crochet) you usually start your double crochet stitch in the 3rd chain from the hook.
YO, and insert hook into 3rd ch from hook.
YO once more and pull through the last 2 loops on the hook
