hi, i am planning to build a static screen (i think that what it's called). i went to our local fabric shop today and they had a roll of blackout material for £4.99 per meter at 54" wide. when i looked at it (having not seen any before) it was white on both sides, one side was lightly fluffy the other smooth. my question is, which side do i project against fluffy or smooth? the material was quite thick, does this sound like the stuff you guys are using. by the way i will be using it with my HS50, currently i have a matt white painted rectangle on the wall. cheers, Jason.
