I love Aurefil thread, but also use Mettler and Gutterman. I tend to use Mettler or Gutterman more frequently because only one LQS carries Aurefil and her selection is very limited. I rarely get the forethought to buy online, but am seriously thinking about getting one of their thread collections for my use. I tried Coats and Clark but did not like it - it frayed and fuzzed all over the place!
