I put a line of Command hooks close to the ceiling. on one wall in my sewing room. I use curtain rings with clips to hold a large piece of white flannel. This is my design wall. It is perpendicular to my sewing machine, which I don't think really matters. I like to stand back and look at my quilts. I also take cell phone pictures of my blocks before sewing them together.
If needed, I can unclip the flannel and then hang a finished quilt.
