Granny Square-Esque Crochet Edging
This is a simple little crochet edging that looks a bit like granny squares with a loop at the bottom. The edging is worked top to bottom rather than side to side as you will see once you give it a try. The only drawback with this particular crochet edging is that it will only look nice if you end after making one of the bottom loops which may make it too wide or narrow for whatever item you wish to attach it to.
It can be made with any weight yarn or needle size though it will loose a bit of the lacy-ness if you use a textured yarn.
The pattern is fairly easy and repetitive once you get going but it is a bit unforgiving if you get a little sloppy with your stitches.
