Old rothco BDU work perfect and are often cheaper than buying scrim. Two pairs of pants got me a hat and a rifle. Mist some spray paints over if you're worried about IR but remember you're never fully invisible in this era. Do a very soft press to get big drops and boom you got DIY decaying leaves. Never was in service but I've been doing scrim/camo for 20 years and I cringe at premade stuff a little. Although I'm very very patient and that's not everyone so it's still cool/suggested to mix materials. My biggest gripe is pricing vs effectiveness.
