I am in the process of moving and will be re-organizing my sewing room in a couple of months. However, I HAD my fabric organized by color. Large cuts were on the large plastic organizer cards and stored upright on open book shelves according to color. Fat Quarters and other similarly sized pieces were stored on the smaller plastic cards and sorted by color in clear plastic stacking boxes in an armoire. Then I have two rolling drawer sets (3 drawers in each) for scraps....also sorted by color: RedsPinks, Blues/Purples, Greens/Browns, Oranges/Yellows, White, Black. I am not a follower of designers so the color sorting is by far the easiest for me. I also store short-term specific projects in pizza boxes just to keep the instructions/fabric together. The KISS Method: Keep It Simple, Stupid ....is my motto.
