ONE strand of our Petites Thread is equivalent to TWO strands of floss. There is no separating floss, no tangling, you can cut to any length and tidy storage with no loss of color identity. Make a more beautiful, bolder statement on your quilting, serging, embroidery, handwork and other decorative projects with Sulky 12 Wt. Cotton thread, which is 40% thicker than 30 Wt. All Sulky Cotton Threads are premier quality, long staple, highly mercerized Egyptian cotton with a matte finish to create a soft, warm, natural look and feel.
