I am on a mission to remake this hat I used to have and love, and was stolen at a house party!!I'm a bit of a beginner to crochet - all I've made is part of a hat and a little coin purse. But I'm determined.Can you identify the kind of stitch used on this hat?! And also how thick the wool may be? Unfortunately these are all the pictures I have wearing the hat.I thought it might be a moss stitch but I have no idea. And how to make the puffy rim... The rim of the hat was really nice on my ears - kept them super warm!Thanks.
