While I have been sick my husband has recovered my design wall with plain white. I got diaper flannel at 27" wide which fit perfect over my 2 foot wide panels. I think it makes a huge difference visually. I don't know how folks work without a design wall. If you don't have room for a permanent one, try a temporary one: sew dowel pockets on both edges of flannel. Stick dowels thru tie string to the 2 ends of top dowel and hang. roll up to store when not in use.
being able to stand back and see your work will change your life! I swear! Quilters Rock!
