Getting creative with Tyvek

I've acquired several pairs of protective overalls that are Tyvek, brand new still in their packs. Quite a lightweight, soft version of Tyvek. Looking for creative ideas to fashion some UL kit from the fabric so please reply with your ideas. I don't envisage slipping into them for wet-weather protection
I'm thinking more of gear storage or whatever else you can think of.
Extra points for creativity.... Interested in how to join the material too.
