So, I'm converting my 2'x4' gobo's into PRD diffusors on one side. I've heard that repetition is bad, but what if I stack two of these 18"x18" designs (
http://www.pmerecords.com/Diffusor.cfm) to make a vertical 18"x36" rectangle?
If doing this is a no-no, then what design (mac-friendly) can I use to build two 2'x4' PRDs to screw onto my gobo's?
