This 4-ply rayon thread is woven with three strands of metallic, giving it a highly textured and intensely sparkling surface. Comparable in weight to a #8 perle cotton, Sizzle™ is stiffer and heaver with a coarse surface that makes a "sizzling" noise when you run your fingers across it. This is the ultimate thread when you want to add a lot of texture, dimension, or eye-catching stitches to any project. Sizzle™ can be easily interchanged with Razzle™ and Dazzle™ in most applications.
