Tried it first in cotton"

I had a little red cotton at hand and a G hook and started this hat from "The Happy Hooker" by Debbie Stoller. It fits the foam head, but not mine. It is more a kid size, so I'll probably give to one of the nieces. It is a simple pattern, all in double crochet. It calls for Red Heart worsted yarn and an H hook. I have lots of Red Heart and the right hook. It crocheted up so quickly I am going to give it a try and do it with the right materials
