This is one of my top favorite crochet edging because of its 3D effect and simple technique.

For the inexperienced eye, it may look like a picot edge, but it’s not. When blocked, it has a spiky look and when unblocked it curls on its self like a Roly Poly and gives the 3D picot look.

This edging could be used for any crochet or knitted project. Just make sure the number of stitches in your raw edge is devisable by three.

I personally think it’s the best edging for granny squares because when stretched open its spiky shape mirrors the 3 double crochet clusters in the classical granny square.
