The zombie was actually designed by my brother's girlfriend, but I saw it and loved it so I stenciled it.
My friends is mechanic and he got me some airbags which are made out of kevlar, which is bullet proof.
The inside has a removable padded wall for your laptop and two large pockets.
The bag is lined with cardboard, covered in masking tape, batting, and combed cotton fabric (aka, an old t-shirt).
The straps are old t-shirts with interfacing and a rope for added stability. Laptops are heavy.
Th zombie city was not actually my original design for the bag, but I am please with the way it turned out.

The only thing I had to buy for this project was the interfacing for the handles, all the other material I had laying around. If someone is interested, I will make this item again with a tutorial.
