My sewing room has plastic bins stackable bins tht pull out like drawers. I have three stacks of them floor to ceiling, probably two dozen total. A bin for each project/kit that has is ready to go--I think of them like airplanes in a landing pattern. A couple bins for misc batting scraps--black, cotton, poly. A bin for binding...I cut and iron the binding for a quilt before I send it to the LA that way I dont use the fabric by mistake. Each WIP has a bin. UFO's on the other hand are put all together in a BIG plastic tote that is pushed under a bed.
Those are all neat but in the bins with just fabric in them by color--my "stash", the material is just wadded and stuck in there.
