The same 12 wt. cotton thread as the Sulky Blendables on a petite 50 yds. snap-end spool. It is ideal for handwork because 1 strand of this 12 wt. cotton equals 2 strands of a typical embroidery floss. So, you can take it off the spool and start to stitch immediately. It is also a terrific thread for machine work. Case has all 80 Petites colors - 66 solids and 14 blendables.|n|A $162.15 value if purchased separately!
