I wish I had a design wall! I just lay out an old quilt on the floor, lay my stuff out, then roll it up. I take lay it across my bed (my machine is in my bedroom- would also love to have an actual quilting space!) and unroll it as I go. I try to sew it all together fairly soon after I've rolled it up so it doesn't all get crunched up and have to be pressed again before I can sew...
