Have you used Kingstar metallic thread yet,you don't need to change needle to a metallic one I have used it a lot had no problems

Berny, this is the metallic thread that I have used for over 8 years and I love it.

I've seen this thread, but haven't used it. I had picked up some metallic thread (no idea what brand it is) sale and when I finally used it I had no problems with it. Later I got a few sulky and when I tried it I had a little bit of problems, but got the job done!
