I do lots of embroidery, so I have LOTS of thread. I got one of the multi drawer roller carts at JoAnn's. The drawers are different colors, so, I have red thread in the red drawer and so on. For general sewing or other speciality threads, I have red plastic boxes that I got at the hardware store. I have them lined up on the divider in my sewing studio. No, they are not covered, but don't seem to get much dust. I just may cover them with thin vinyl.
