I had a ball of Rowan Felted Tweed leftover from my Tyrolean sweater, since I decided not to do the embroidery. It was just the perfect amount for a new hat.
I found a free pattern on Ravelry, called Tweedy Tam by Lydia McNeil. It is such a quick, easy and adorable pattern, I highly recommend it. This tam was finished in under a week.
I wove a doubled strand of thin black elastic on the inside edge. It makes the hat stay on perfectly, and is comfortable even if I put all my hair into the hat.
I decreased the top a bit earlier th an the pattern called for, since I don't like when hats look like teats. (Sorry, I'm from South Florida, we're boob obsessed).
If I were to do it over, I would make it larger. That's not necessarily the patterns fault, though. I don't think I increased enough stitches, and didn't pay attention to the gauge. Please note, the pattern is written well, any mistakes are my fault!
