I'm guessing you found a solution but if not, what I did was to get a full size bed topper from Walmart, 2 of the 3M curtain rod hangers and a curtain rod. I poked holes in the topper and used zip ties to make loops. I strung the topper onto the curtain rod with the waffle side towards the wall and the smooth side out. I cut it to length. It works great. I can either pin or press pieces against it and they stay on. The toppers come in different bed sizes and are pretty inexpensive.
