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. Remember ONE strand of 12 Wt. Cotton equals TWO strands of the typical floss and a 50-yard spool equal 2 skeins of floss, so you get more for your money.
