Okay. So I bought some red wool to make Tom a hat the same time we bought the ivory wool for the tunic but I just didn't get around to doing it until now. I used a black fleece hat that was laying around as my pattern to cut four pieces of the felted wool. Then I just overcast or whipstitched or whatever the correct term is the edges together.
the cut pieces
the finished hat
I think I actually prefer it with the stitching on the outside
