Masking for Retractable Screen
I've recently moved into a house that has a projection system. The screen is a da-lite 4:3 ratio screen. I'd like to add some masking to the top to make it 16:10. Are there any suggested products out there? I've seen some black felt tape but that looks to be for fixed screens and I worry it wouldn't last on a retractable screen. Perhaps there is a better product out there?
