From Treenway Silks, this 6-strand spun silk floss can be separated and use as few or as many strands together as you choose to create the right size thread for your stitching project.  Each of the individual 6 strands is a 2-ply thread for pleasurable stitching,

Each card has 10 yards of beautiful hand-dyed silk thread.  The silk is from the Bombyx mori silk worm, often referred to as "mulberry" silk.   There’s nothing else like silk! Silk is strong yet delicate, luxurious and lustrous.
