This was one of the three R2D2 hats I made for some of the boys I know that are big Star Wars fans. There are a few different ways that you can make a beanie like this. I tried a few different options and will continue to post pictures and methods I used for these hats. This was my first attempt. Although it came out a little bit smaller than I had anticipated it still fit my 10 yr old brother, who loved this.
