Use June Taylor racks on the wall for all embroidery threads, small and large spools. Use the plastic covers over them. Have all quilting threads in a large round plastic container. Put all serger spools in a round bedcover bag. Store all-purpose threads in round plastic containers of which I have six. Store bobbing thread in its own box. Also have 2 large plastic containers spinach comes in to store any odds and ends or excess. Probably have to much thread, but seldom purchase any except for a class I may be taking.
