Jute netting in timber
Drums and barrels all screwed together
Used crating from China
Old cars or hearses and trucks or buses with no gas tanks
Tarps painted like circus signage
Used metal buildings salvaged

Depends on what is industrial waste material in your area?
PVC sheets, sheet metal, fiberglass panels, tar paper shacks, log cabins, bottles all cemented together? Dryer lint and acrylic resin? Old walk in coolers? Piles of dirt or real rocks.
Each situation is different. In these days it might infact be cheaper to buy new from Home Depot than spend $50 a day in gas getting crap from somewhere. Sometimes free costs more than new but it has the look you want.

Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
