There are some really good ideas here! Love the idea of the parmesan container for used needles and rotary cutters. I'm always fearful when I just toss them in the trash. I have one that is about empty, guess what I'll be using it for!
For me, I use old CD racks to hold my fat quarters. Yes, they are exposed and not put away, but I do use them quickly so there is no fading and little to no dust. I like being able to see my small gems out in plain site. It makes the sewing room bright and cheerful, and also gives me ideas while working on a current project.
