I only use an 80/12 or 70/10 needle, polyester monofilament in top and regular thread in bottom. Spool is fussy unless i put it behind the machine in a large, deep coffee cup. Has to move on its own. I also loosen the tension just a tad. I check each of these things when I use this thread, and have no problems.

I had to find the correct size needle and then didn't have any problems. That worked for me...

Don't use the cutter it will really mess it up. Voice of experience!

Now I am excited to try again! Thanks for the suggestions!

I must be thread challenged....never had any luck with any of the clear/black monofiliment or whatever type plastic threads....drove me nuts so they left to a friend that loved them and knew how to make them work.

Personally, I won't use the clear thread.
