I want to make my own screen, viewable size 120x67.5 cm (47.2"x26.6").
I am about to buy the screen material and wonder:
if I want a black border of about 5cm (2"), how much more do I need to fixate the material firmly to the frame (stapling the material in wood)? Will 1.5" be enough?
So the size of the material to buy will be (47.2+2+1.5=) 50.7" x (26.6+2+1.5=) 30.1"
Will that be enough?
