This is how I did it: All whites, off whites, cremes and blacks go together. Then comes all my solids, then my stripes, then dots. Next comes my whites with black prints and blacks with white print. Next is prodominently black fabrics. Then predominately cream and brown colored fabrics . Holidays are together, Batiks are together, Asian are together, College fabrics together and special collections such as Dr. Seuss are together. Then I sort the rest of my fabric by ROY G. BIV, the colors of the rainbow. Whichever color is most dominant dictates what color group it goes in.
