000 - 099 Caron WaterliliesA twelve ply hand dyed variegated silk. It gives a subtle sheen when stitched and has particularly good light reflection qualities. Use a single ply for very fine work or as many plies as necessary to suit stitch and ground fabric. Many of the colors match Watercolours and Wildflowers, but because the silk fibers take the dye differently, they may be more subdued.
