Well, last night on my way home I ran to JoAnn's (closest to me) and grabbed some more of the Gütermann thread. Let me tell you, my machine was SO much happier last night. The Coats & Clark that I had in there, I threw out. I am definatley going to have to find the Aurifil or King Tut brands and try them!!! Thank you all so much!!!
Great to know what a lot of people use.
