I have two tackle boxes. Brand name Magnum. Two sided, lots of adjustable compartments. I have my embroidery thread in them sorted by number (I have all the DMC thread up to approx. year 2000. Haven't kept up with new colors since then. I also have some clear two sided boxes from the sports section of Wal Mart that I keep thread in. They snap together and are must less expensive than the boxes from a quilting store/site.
