I use foam board, make minnie bolts, stand them up in my old china hutch and in cupboards, open the door and I can see what I have at a glance.1/2 yard or smaller are sorted by color, kept in baskets and considered Lg scraps, scraps from sewing is trimed into largest usable size, strips and or squares and kept in labeled baskets. When starting a project, after selecting fabric I always check my scrap bins to see if anything will work first before cutting into yardage.
