I used a crab stitch edging on my hexagon blanket (original post HERE) but I found some of the explanations of how to do crab stitch not entirely clear, so here is my own explanation for anyone who hasn’t done it before but would like to try.
A few views as the edging appeared on the blanket.
Here is the picture tutorial
Crab stitch is worked in the opposite direction to normal. That is from left to right for right-handers like me.
It is best worked on a base row of dc (US sc) and I started by doing 1ch just to loosen it up.
