Check out this Zombie bag from doxieart @ Craftster! – “Bag is 12 by 10 by 2… It’s made from vinyl, lining fabric, d rings, snaps, a zipper, and nylon webbing. The red is clear vinyl which I colored red with a red sharpie. I made the pattern myself but it’s just 2 pieces for the flap, 2 outter of vinyl and two inner of the lining fabric. then a strip that connects the sides.” – Link.
