DIY Comic Book Baseball Cap Tutorial from aetienne here. I’ve seen lots of comic book inspired handbags, jewelry, and fashion for the coming seasons on lots of fashion blogs. This tutorial comes from Lenne who also came up with some of my favorite past posts: DIY Burberry Prorsum F/W10-11 Inspired Zipper Blazer here and the DIY Mirrored Collar Using CDs here.
