I put them by color then I "play" with them and get them all messed up If I buy fabrics for a project I try to keep them together so I won't use it for something else. I can never keep fabrics organized. I never seem to have the right amt. of fabric for a project in my stash so I have go buy more. and of course I buy a little extra so I won't run out if I cut something wrong. On my I am a lost cause. If you figure out the correct way to do this please give me directions.
