KCS pearl shiny metallic thread is a divisible, six-strand glistening thread that will add a twinkle and special touches to your handmade. It has a pearl shine on its surface. This 100% polyester thread is colorfast and tarnish resistant.Each pack consists of six different beautiful colors. The thread consists of six size 25 easily separated strands. Use it on its own or combine it with a strand of cotton floss for a touch of sparkle. Metallic thread is for experienced embroiderers only, as it's a lot more difficult to work with than cotton.For the best stitching , work with a shorter length of thread (try 12 inches). This will help keep the fibers fresh and prevent fraying. If the thread becomes twisted while stitching, drop the needle and let it unwind itself.
