I just recently bought some Aurifil 50wt. 2 ply cotton. I had heard so many say what a good thread it was, I thought I would give it a try. Boy am I impressed. So smooth & very little lint. I normally use Mettler cotton in either 40wt or 50wt. and I'm sure I will continue to use it. But, now that I have used the Aurifil, it has won me over. More Aurifil purchases in my future.
