This six ply strandable floss is made off 100% bamboo. It’s not cotton and it’s not silk BUT it has a matte cotton finish and it feels silky smooth when you stitch with it! Use it 4 ply on 18 ct. canvas. For cross stitch, use it 2 ply on 14 ct. – it’s especially appropriate for samplers in these delightful soft finish colors. 20 yards per card in more than 100 yummy colors. The colors in the drop down menu are those we have available as of November, 2014. YOU MAY ORDER ANY COLOR YOU WISH but if we don’t have the amount you need, we will ask you to purchase at least 3 of the 6 cards that we must order. The Mandarin Floss M800 is the whitest white, we have in stock! Keep this in mind for wonderful white turkey work on your Santa beards, cuffs and of course on polar bears!
