I organize by color excluding stripes, flannels and collections. Those I try to keep together. Oh yes, kiddie fabrics are usually separate too. Guess that's not much by color is it now???? Anyway, most are by color, on comic book boards or if more than 5 yds., I have them on bolts. Fat quarters are by colors in plastic shoebox size totes and scrapes are by size. When it doesn't fit the comic book board, it becomes a fat quarter or scrap.
