I have two four drawer units stacked upon two wood storage drawers. It stands in the corner like a tower. I also put small sewing needs in a couple of the drawer and embroidery threads separated from the sewing threads. I have a piece of fabric hanging down on the side where the sun could fade the colors. I thought of lining the drawers inside with a paper that would not allow the sun through. But they are so full I think it would get scrunched up and be worthless. That being said, I also have a sewing desk and two of the drawers have regular thread size spools separated out by color with plastic baggies. I just lift the baggie out as needed and see which color is best.
It is convenient to have them close by and easy to grab.
