I posted this some time ago, but here it is again.
We put up a long traverse curtain rod on the wall over my door to the sewing room. I got a queen size flannel sheet and put the curtain hooks through the top section of the sheet where it is 3x thick. Then we hung it on the traverse rod. Now I can pull it open or closed, and there is plenty of room for more than one project on it. I do use pins to hold the pieces on so they don't fly off when I open/close the "curtain" design wall. I love it!!
