I use the Aurafil on the orange spool. It is expensive but I have not had any problems with it. Purchase at your LQS. I was also told to use a light grey on everything as it is so neutral it does not shoe. (Haven't done an all white or all black quilt though. I would have to think about that one a while.) Also, be sure that you are using the correct needle i.e. 85/10. I think those are the numbers that go together. Some needle holes are smaller than others. Hope this helps.
