I found a small rolling rack at a thrift store. I think it was made to go between or beside your washer and dryer. It is only about 24"H and 8"W, with 3 shelves. The top shelf has a tall glass with marking pencils, pens, straight pins, small sissors, things I use a lot. The 2nd shelf has thread, the third shelf has safety pins, bobbin holder, small plastic bag with cleaning brushes. It holds everything I use at both machines, and is so small and easy to move between my sewing machines and it only cost $.75!
I made 2 design walls out of 4'x8' foam insulation. The just stand against whatever wall I'm not using. They are light weight, and I can keep BOM's out where I can see them. Also I sandwich my quilts on my design boards because I am getting too old to get down an my hands and knees.
