Yeah it's that whole cut to straight thing. Not my strength. Going to try a strip of the baby bumper stuff and see if it looks good. It's only for frame aesthetics anyway.
Felt tape is on, screen looks fantastic and displays an unbelievable image.
For the benefit of the next guy or gal. Don't freak if the screen material is folded and after stretching you still see fold lines. Picture is great, fold line s unnoticeable when image is on screen & I have to think over time gravity will in any event work its magic on the invisible (when viewing video) folds.
Very happy with my screen, thanks MM for the help.
