Previously, I had racks my DH made and placed above the windows. Yes, there was a dust problem, but not horrible as I have air filtration in every room. Now I have 4 drawers. One of the dresser drawers (Sterilite, plastic stackable dressers which I got at Walmart) is plain cone thread. Another is metallics and variable cones. I have 2 much smaller drawers for smaller plain threads, many for hand work. This set up works well for me, although the plain cone drawer is VERY full. All of my thread is protected from dust and from light damage.
