RichardH,
My projector is still with Panasonic - or more likely it's still sitting at the dealers waiting to be sent; I only returned it on Saturday.
I didn't buy a custom-built screen; I ordered a standard roller-blind in a light grey blackout fabric. The colour is an almost exact match for Icestorm 5, the finish is a good smooth matt and the blackout property was necessary because it has to hang over a window. I plan to make a black frame (probably MDF or similar) which the screen can slide down behind.
The blind seems to hang well, though there is a very slight ripple towards the lower right-hand corner which I hope won't prove to be a problem.
All I need now is the damned projector.
