it shouldnt be. did you have it custom made? what screen material did you use or chose?

the only way to see if it would cause a problem would be using the projector you're getting. or, you can try using a flourescent bulb, and see if the light would 'show' you the crease.

just to make sure we're both on the same page.

are we talking about a crease or a fold?
or are we talking about two pieces of fabric, sewn together?

glad to see your still around bud. and yes, the metric system is a pain in the butt...

about risers, well, im sure a couple of experts here can chime in.
