After installing a double sided backdrop to visually separate two different scenes, I'm faced with the question of how to hide or conceal the holes that rail must run through. There was an article in MR awhile back I must locate, but I was wondering how anyone here who has faced this type of "problem" decided on how to go about it. I've attached a rough drawing of the area under consideration with a couple of ideas! Thanks in advance! Matt--Hershey, Pa.
