Awww, I want this.
I don’t spend a lot of time on Etsy but perhaps I should. Seen here is an R2D2 knit hat from Etsy seller craftandcrochet. This is super cool and extra geeky. It’s only $22.50 and will be made in 2-3 days. At the price, you kind of have to get one. Hit the link for the Etsy page and support.
