Now that is a stash!!!!! I sort mine by color too, with some special boxes like 30's, civil war, thimbeberries, black/white, paisley, plaids/stripes (from shirts) - and then there are the stacks that don't have a home yet. I use plastic shoebox size boxes and when the lids don't fit anymore then it is time to raid the box for a quilt. I also store by size - 1.5, 2, 2.5 squares and now 2.5 strips. I don't purchase fabric unless it is for a specific project and since I do a lot of scrappy quilts, it is usually for borders/bindings/backs. All my stuff in boxes is pretty small - FQ or smaller - I really don't have yardage. I am green with envy!!!
