Last year I went through ALL of my fabric and found duplicates in more than one color. Everything is organized by theme/ color now. I do the same thing though about buying fabric for a project--I put the pattern in one of those scrapbooking clear boxes and I put the fabric in there as I purchase it. It helps to organize when I am working on a project also. My problem is I'm always getting excited about new projects when I still have all of those others waiting to be done.
