Superior is....superior. Go to their site and sign up for their newsletter and daily specials (if you wish). I use their So Fine for piecing. I buy it by the cone - 3,250 in the large cone. Never had any problems with the So Fine and my basics are white, cream, medium gray and black. I use the Bottom Line for hand work. Their newsletter has a lot of information and they are very informative about the application for each of their products as well as needle size. Guess you could say I am a Superior gal! And, no, I don't work for them.
