There is a great tutorial: How to make a design wall fast, easy, and inexpensively.
Have a look under tutorials and see what you think. I'm redoing my sewing space and I do believe that's what's going to be included. Not only is it a design wall, but also a decorative feature.
Personally, I use the back of a table cloth from the dollar store, and that's great for going to retreats, but I'm looking forward to something a little more classy in my sewing room.
