I once had yardage (1 yard and more) very neatly sorted on comic boards by color, with separate sections for batiks, holidays, 30's, flannel, etc. But as time goes on I find that it's less orderly. And the smaller pieces are even worse. I try to keep pieces from one line together, and otherwise sort by color, and/or type of fabric, but it's like cleaning your house - a never ending process. (It is a lot more fun though.)
