I knitted a Yoda hat for my son a while ago but wanted to share it.
My husband really wanted a Yoda knit hat for our son, I was going to buy one for him cause I can only knit scarves and my crocheting skills are horrible. But I found this you tube video and you can do the whole thing using a circular loom which makes it soooo much easier and quicker to knit a hat. The ears can also be done on the loom which is pretty neat. I used to loom knit Barbie dresses as a kid so this was a piece of cake.
