I have to agree with Alison. In a few threads (Empress Mills cottons and Swiss Maid come to mind) the white threads are measurably finer than the coloured equivalents. Whether that is because the dye adds to the bulk of the coloured threads or the bleach takes away from the white I'm not sure, but definitely it's the coloured threads which are thicker.
