Thread > Wonderfil Sizzle 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. Perfect for bobbin work, decorative stitches, couching, tassels and fringes, thread lace, and bead work.
