Hey folks: I'm trying to find answers for an on-going backdrop problem I'm having on my NYC layout. First, let me say that, since my layout is being located in the partially finished basement of the home I'm currently renting, the layout isn't going to be a permanent one but rather a "practice" one for the home I plan to buy or build in the next few years. It is approximately 15' x 12' "around the walls" with a 6'x8' extension accessable from all sides. Now, before you "yell at me", let me also say that the benchwork, track, and most wiring are completed without the conventional rule of "back-drop 1st". The backdrop was originally going to be done first using masonite panels on a 1x1 framework. The problem I then encountered was that the masonite was going to extremely difficult to get down the stairs without being cut up into small pieces and once down there, very hard for me to erect alone. Sooooooooo..... This leads me to try to find a suitable material to use that will be strong, flexible, and most importantly, light-weight. Easily handled by me alone and if possible not needing a support frame work. In case anyone needs to know, the benchwork is open-grid with 2x4 legs. The backdrop needs to be by three walls. Two of them block and the third, wood paneling. It also needs to be 3'high. Coved corners are not necessary. The benchwork itself has about a foot of open space behind it and the walls. Thanks in advance for any tips or suggestions!!! Matt--Chocolatetown, Pa.
