I use grey headliner bought it at Joann's and asked for the cardboard roll it came on. I bought 2 feet and it was I think 5 feet wide. I just sewed the top to slide the cardboard roll inside and use a bunge to hang it on the wall. This way I can roll it up and take it to sewing class when I am working on a project. (Headliner is what it is called and used for things like roof of car, grey because it is a great color to use that doesn't class with your project so you see your colors well) So inexpensive and portable!
