I am building a wearable Coca-Cola can out of a cardboard, 55 gallon drum. I'd like to install a harness inside it to make it more comfortable to wear, but I can't figure out how to attach said harness to the inside of the can. Photos of the can itself and a quick mockup of what I'm thinking. What would you do? Ideally, I'd like most of the weight to rest on the belt, and not on the shoulders.
