I try to stay orgainzed but it does not come naturally to me. Sometimes I think I spend too much time trying to get organized when I could be quilting---. Scraps are the biggest challenge. I won't say problem as anything to do with fabric is enjoyable. Large bins, floor type or table top , take up too much room. What I decided to use is small plastic baskets. The type used as drawer divider/organizers. I labeled these for desirable sizes pieces. They are stackable and when stacked take up limited space. When I am cutting my scraps, I can spread them out and see at a glance which basket they belong in. I file them immediately to illiminate remeasuring later. This is good as I might cut different sized pieces from one fabric scrap. Sizes I chose: 1 1/2", 2", 2 1/2", 3", 3 1/2", 4", 5", 6". I also have a basket for triangles of all sizes as these are continuing to "show up". I make 1/2 squares with these so I have baskets for the 1/2 squares. Most common sizes 1 1/2 and 2 1/2. I would love to hear how you handle this problem.
