I started off by cutting out a circle pattern shape that would provide the coverage for the top bun of my burger. Considering I would be later stuffing the material with padding later on, I decided to make the circle larger than i actually wanted my bag to be (as should you!)

Once I had cut a couple of them out; i then layered and made several holes in order to create that zombie look. Then stuffing it with wadding (you can use anything; reuse old cushions or old toys) Then either hand sew or machine around the edge; furthermore pluming it up to give the right shape.

I then thought about what I would use for lettuce; luckily this was a print on one of my old t shirts that I had just cut out; but you can use anything from old scrap material, to painting old material in acrylics of fabrics paints!
Then gather it through the middle with a needle and sew.

I then hand sewed around the edge, keeping the burger in place; I also had sewn a few through the burger bun to make it look further like a burger bun with the bumps and seeds edge going on..

The for the bottom part of the burger bun; I measured what the burger top measured as now and replicated that into the bottom; then around the edge adding a plastic stiffener to give it shape.

I then focused onto the actual burger eat; I cut out some foam and painted it all, using a variation of brown and green to give it that real zombie texture!!

(using acrylic)

This is the burger when dried.

I then stitched it into the top following a thick red tooth zip to symbolize ketchup; and also attaching it to the bottom half. When it comes to this part your more or less done! Oh I also forgot to mention attaching the straps on; which I had done with the machine, making it into a back pack. For added embellishment, you can do some random red stitching (or any color you want) to give it that rough zombie texture!

Goodluck and I hope you try this at home :3 they are so much fun to make!
