I have been knitting socks for a number of years and my favourite method of using up the leftover wool from each pair used to be to knit a pair of socks with all the extra wool UNTIL I saw this pattern: http://www.redheart.com/free-patterns/knit-roll-brim-hat. I had no idea how much wool I had until I started to knit these hats. I love the pattern and I can whip up a hat in an evening of mind-numbing TV. I have given a couple to my husband, kept one for myself and am giving the rest (with more to come) to the shelter downtown. This is my first post with pics so I hope it works. The plain blue hat was the first one I did with this pattern.....used wool that a friend had donated to me.
(Edited to add a photo now that I read the instructions and figured it out.)
