I have plastic drawer units I bought at Walmart. 2" deep drawers hold spools laying down and organized by color. 6" deep drawers hold cones standing up. I have them under my sewing table. I have more of these drawers in the closet with FQs and scraps in them. The units come in 3 or 5 drawer units (taller ones have wheels) and they snap apart so I arrange them the way I need. I find these to be much less costly than the organizers that JoAnns sells.
