I started to use Glide thread on my longarm and it made a great difference. Then I used it on my Janome Horizon, also with good results. It's strong, thin, nearly lintless and comes in a wonderful array of colors. I'm completely happy with it. People used to avoid polyester thread, thinking it would damage cotton fabrics if seams were stressed by pulling. I don't think it matters and I've had only good results with Glide.
