my janome dealer, told us during a class, that the best thread for quilting is superior threads, if you want a professional looking finish. The king tut egyptian cotton for quilting, and the Bottom Line for bobbins. I use a cheaper thread, polyester, for piecing. The superior is suppose to have virtually no lint. I just bought some, and haven't used it yet for quilting. I am going to though, soon. I have one top, ready to quilt.
