I have some of mine on 3 thread racks on the walls behind the machines. Two of the racks are for serger thread (plus a divided box) and one for smaller spools of machine thread. I have all my Sulky rayons, metallics, sliver, etc in thread boxes with some miscellaneous decorative threads. These at stacked against the wall under the window. I used to help out at the Sulky booth at Quilt Festival with set up and tear down and Fred would let us take our wages in merchandise so I have lots of thread boxes and threads from them.
