QuiltedCat Posted February 14, 2007 Report Share Posted February 14, 2007 Hi Cathy: the Superior cotton prewound bobbins are made by Coates and are cotton. The Bottom Line prewound bobbins (Super BOBs) are poly, not cotton. They run clean without any lint buildup in your bobbin case, or very little. Many longarm operators prefer the SupperBobs (poly) because of a clean, no lint in the bobbin area. It is a very smooth, 60 weight, fine thread.
