It looks like all the DIY screens on this forum are the fixed kind. I'd like to have a pull-down screen; are there easy ways for me to make one myself? I'm currently shooting my X1 onto an off-white wall, and the picture looks very good, but I'd like to experiment with higher contrast materials. I could probably do a fixed screen if nothing else works, but I'd prefer the flexibility that a pull-down would give me. Has anybody tried this?
