I made another beanie last night. I love how quick and easy they are to make. I need to find a few new patterns/variations to try now. I used some wool that I picked up at Big W a couple of weeks ago. It was really cheap, from memory only around $2 or $3. It's actually designed for felting, but it worked quite well for this beanie and was surprisingly easy to crochet with. I used about 1.5 balls - so pretty cheap for a wool beanie! The manufacturer is Sean Sheep and this particular wool is called Beulah. It comes in quite a few different shade combinations.
