Update: I'm going to start doing this regimen right now! Just took down a month of box braids and I now have cornrows in. There are just too many options using this regimen that I can do. Besides braids and cornrows (which I typically wear into a bun or claw clip), I think I'll wear them with a phony puff, under a wig, a cute hat, or head scarf, and I'll definitely try them with crochets really soon. You can't beat this!
But I'm still trying to decide whether to try the water wave crochet or kinky twists crochets first...
