6/10/14: I pulled these out of “Area 51” because I’ve been on a wip kick.
The first footlet was finished last year sometime.

Changed the edging so it wouldn’t slip off my heel, as follows;

Edging:

1. Sc in every other st
2. Ch 2, sc 4, skip 1, repeat around
3. Ch 2, sc 3, skip 1, repeat,
4. Same as picot crochet edging.
