I think I'm on a Zombie kick.

EDITThanks for all the comments. I'll just answer all the questions here.
The bag is made from vinyl, nylon webbing, snaps, 2 D rings, lining fabric and a zipper.
I've been working with vinyl for a while, I love it. I try and keep my stitch length set at 3, any longer and the bag could fall apart and shorter and you just preforate the vinyl and it could tear.
The bag is 12 X 10 X 2 inches, it's the smallest messenger bag I make, any smaller and I can't get all my stuff in it.
For the red areas I bought clear vinyl and colored it with a red sharpie, then stitched it on with clear thread.
I am working on the tutorial, it's really simple, it's the die cutting part that I'm having problems with but it will be up very soon. In the mean time I'd be happy to answer any questions about working with the vinyl or how to make you own patterns. I use tracing paper to work my patterns out wth because I can fold it and see through it. After I perfect the pattern I put it on poster board so it's easier to use.
Again thanks for all the comments, you all rock!
