The loom knit hat is finished! For this one I knit in a ribbed pattern, k1p1 for the entire hat, then finished it with a flat seam along the top instead of gathering it. I did make the hat a little bit long, but the edge can be folded over to make a brim.
Now I need to get started on hat number seven; I'm thinking of doing a variation of the awareness ribbon pattern I used in my last batch of charity hats. Fingers crossed it turns out as well as I am imagining.
