Left 4 Dead Failkit Backpack

So asked and me to go to Metrocon with her. I decided I'd go as a makeshift Satanic hunter thing, and decided to rig this up.

It's a string backpack I got for donating blood, but I chipped off the letters that were originally on there (iDonate then the FL Blood Services logo n such), painted it black, then the red on top. Originally the red was going to cover the whole middle part (between the gray lines), but I was running low on acrylics and thought that a grungy look would be much more fitting for a Left 4 Dead prop.

The original rope on it was chewed up by the Esteemed Dr. Gonzo, Attorney at Law, so I replaced it with old boot laces and added the key rings for why-not reasoning.

I'm thinking of having a pill bottle filled with Skittles or something, but I dunno how well that'd go over with con rules ('case you haven't guessed, I've never been to one of these things before).

See you in Tampa.
