This was a silly side project that I finished a month or so ago. I've seen similar things around before, and thought I would just see if I could make this sort of thing myself. The gray one is mine, the green one was a gift for my mate, Static. I think they are adorable, though admittedly I haven't actually worn mine in public yet :P
I'd be willing to do these as commissions; I'm thinking around $60-$65 for solid colored ones like these.
