Chameleon Rayon six-strand thread x 8-metre skein. Rayon is a rich, lustrous thread with a shiny finish. Dyed on a DMC satin base, this gorgeous range of colourfast rayon is ideal for a wide range of embroidery styles and stitches and can be used instead of silk. This is the thread that I use when making loose, frilly French knots and I think bullion knots are lovely in this thread. Also useful for making long hair in a design.
