Somewhere I have exactly what you need. A copy of the U.S.A. Camouflage TM from ~1943. I just rescued it and to pry the pages apart! But I put where it would be safe and we all know what happens then. You can't find it!!! But it did read it closely and they only issued a net and nothing else and the "decoration" was left up to the soldiers. They were very empathic that the soldiers use local material for camouflage and pointed out that non-local plants and material stood out as bad and sometimes worse than no camoflage at all!* The soldier also had to pay attention to the point of view of the enemy and make sure that the camoflage matched what would be in the background from the enemy's view point. In short, there was no brown and green burlap dressed netting. There's was only plain netting and the soldiers had use local plants, paint, soot, mud, burlap and other material to make their own camouflage. The TM did specifically recommend torn burlap as a good base material since it broke up shapes without attracting attention to itself. You should try to locate a copy of that TM. It was very interesting reading and I was surprised that it actually had color pictures! I've seen color pictures in very few TMs and never in one that old!
*FWIW we didn't learn that lesson very well. In VietNam we (yes, me!) were dropping radio transmitters disguised as plants behind enemy lines and using them to listen for convoys and other traffic carrying weapons and supplies to the south. If the analyst heard anything that that they thought were supplies or troops heading south they called in air strikes on them. It never worked well and years later we learned why, the dimwits that designed them disguised them as plants that are not native to VietNam and the VC and the locals spotted them almost immediately!
I see that the U.S.A. is now issuing plastic "camouflage" but AFIK they only have two basic patterns; woods green and desert tan. They STILL haven't learned their lesson! Not all woods look alike and not all are green. Same with deserts, they don't all look alike and not all are tan!
If you're going to use your camouflage for shows you'll have to "redecorate" it for every different setting so that means just about every show! And even then you'll have to try and keep the audience confined to one area so that they have the proper background to match the camouflage.
Let me know how it turns out!
