years ago, I found a smaller plastic cabinet that had six small covered containers on the shelves. These were just high enough to hold my RA cones of thread and I can see the colors through the sides. It works well for me but I had to get two of them to hold all the colors plus some other threads I have. I can easily remove one of the containers and find the specific spool. Do you hang your threads or are they placed in the drawers on your holders?
