I have used a variety of subpar materials that still get the job done because I never can afford the scrim. I've used natural scrim (https://www.onlinefabricstore.com/natural-cotton-scrim-fabric-.htm). It is very soft though and hard to pull perfectly tight, but I used it for a ship sail and was able to paint a compass on the front and rear project pretty well. I have also made curtains out of it to do a front light, back light ghost illusion. I am using it this year for a small round projection screen that I will paint like a clock face. Then...last year, I needed black. Crazy find, but I found that this Better than Paper (https://www.amazon.com/Black-Better-Paper-Bulletin-Board/dp/B0792HCFTJ?th=1) worked surprisingly well for my black and white video rear projection and shadow puppet scenes.
