I got a pattern for these from All People Quilt a while ago, but can't locate it right now.
Anyway, don't think of it just for girls. My grandson saw one that I had made and asked for one. I bought a "skull" patterned bandana for $1 at WalMart, fused it to lightweight interfacing for body and made him one that he really thought was "cool".
I'll look for that pattern and my pictures later......
