Last year when we redid my sewing room, I made over an old medicine cabinet. It was an oak cabinet with a mirror in the door. I took the mirror out and had glass cut to fit. Now, I have 4 -5 shelves that I can arrange the spools in color order, about 3 large spools deep. It works great. I did have a spool rack that hung in the open on the wall. I didn't like the dust they collected. This keeps them neat and clean...and clearly visible.
