used plain black fabric and overlapped it and Scotch taped it on the back of the piece of cardboard that came with the frame. I used scotch tape to hold the air-tites to the fabric. It doesn't hurt the air-tites and it holds them securely to the fabric. I will let you all know how long it lasts before they fall. lol I kinda liked the looks of this picture taken outside. lol Thank you all for your kind words. Have a great night, Mark
