Truthfully, I had a longarm for 3 years before I really got into it. I guess I was a little afraid of it. In the beginning I got eyelashes too. Drove me crazy. I don't have a stitch regulator so I found I was speeding up too much on the long sweeps and such. So I got eyelashes. About 2 years ago I tried Glide thread. It is a trilobal (?) polyester. I have not had to adjust my tension since then!! (Occasionally I get eyelashes when I forget and go too fast, but I'm getting better at being relaxed and smooth.) That's all I use. I know some will say it should be cotton, but I'm happy with it, and it has survived many washings. Good luck!! Ann
