ruffles - crochet edging

I'm crazy about two things lately, ruffles and crochet.  I've been practicing some edging techniques and came up with this ruffled one on my own.  It's super easy and relatively quick.

Supplies:

Plain Dish Towel

1 Ball Size 10 Mercerized Cotton Thread

Size 8 Crochet Hook 
Yarn Needle
