I used plastic covered storage boxes for my stash. Each color has a box. As a color expands and outgrows it's box, I transfer it to a larger one. I've several sizes of boxes right now and they are stacked on top of each other in several stacks on the perimeter of my sewing room. I've labeled both the top and the ends of the boxes, so it's easy to find the box I want. This works for me and I can't ever imagine having it folded and stored in open shelving like lots of you people do.
