You may have answered my question in your post, but I must have missed it. The question is how do you keep the 4 pieces of your wall together, and can they be separated if necessary. Being able to disassemble and store somewhere else is important for me because, right now I just hang a 8'x8' piece of felt over my sliding closet doors, but it is so floppy. Having the insulated board for stabilization would be easier to keep things from falling off and easier to pin the heavier pieces on. Thanks in advance for the added/repeated info. BTW you and your dh did a great job on the entire space.
