I try...VERY hard, to pick up before I leave the sewing room each time. I have clear covered shoe boxes from Walmart that I store fat quarters and scraps in, 2 for each color (or color family). One holds fat quarters and the other holds smaller scraps...teeny scraps go in a container of it's own of all colors and 2 1/2" strips another. I also have a container where smaller strips go in for crocheted rag rugs or placements. I don't believe mine mate during lights out...I just have a terrible fabric fetish!! I fall in love with fabric and have to have some of it from just about everywhere I go.
