I bought two 4x8 sheets of foam board insulation at Lowes, I think it was about $4 a board. I stapled felt on the boards and hung them side by side on my sewing room wall. I have a 8 ft square design wall :D I use a step stool to reach the top when I'm making a king size quilt. The foam board is lightweight and easy to cut if you want a smaller size. I just stapled it to the wall with a staple gun. I've moved it several times from one room to another with no problem. I bought another one and made a four ft. square and 4 two foot squares covered in felt. I use these for small projects, taking block pieces to the machine, etc. I always find a use for the small felt covered boards.
