Eddie, when you build your gobo save out some ofnthe foam for the outer surface(the side that won't get folded to the inside.)

I should take some photos of the gobo in my roon i use it in now. My 'booth' is much better now as the backside is an open clothes closet with lots of heavy winter coats in it that we actually dont use too much out here in colorado.

I also fashioned a lyrics hanger that goes over top but not so low that it causes reflection issues into the mic. It uses those big binder clips.
