I had the shelf already. It was in our dining room of our old house, but it didn't fit in the new so I took it for my sewing room. It was wood colored so I painted it (behr embellished blue is the color). I Love the way it looks now. Anyway, I got a cheap roll up shade and some gridded flannel. I glued the flannel to the shade using Aleene's Fabric Fusion. Hint: let it dry well before rolling up the shade.
Then we mounted the hardware to the inside of the shelf brackets and installed the shade. It rolls down easily. A little touchy going up but I'm getting the hang of it. I had to increase the tension because of the extra weight of the flannel. I've never had a design wall so I have no idea how much I'll use it but I'm happy to have it. I paid about $23 for the roller shade, a dollar or two for the brackets, and about $20 for the flannel (it was a little expensive but I wanted the grid). The width of the shade is about 60".
