Yes, my dealer sells Aurifil, and it is expensive. She sells about any kind you can think of, and it seems to me, it is all expensive. Used the Aurifil, and yes, it is nice thread, but I do think there are many nice threads on the market. I realize that polyester would give much less lint, but any article I read, they say to use cotton. I am always open for new ideas. Would poly be the way to go. I don't have to worry for a while, because I have quite a bit of thread to get used up. I know I have used Gutermann in my Viking Designer ! I really enjoy everyone's input on topics. I know that is how I learn. And I know I have a lot to learn!!!!!!!!!!
