linkd - and you're laying the folded fabric flat? Or standing it up like a book?
I'm having trouble envisioning this...you're ending up with the folded fabric 3" wide by 1/2 inch thick and...how deep?
I appreciate all the ideas and feedback I'm getting! As soon as I get the room done I'll post piles of pictures.

I'm HOPING it'll be completely done before end of the month but that's going to depend on the painter's schedule.
