jigs1324, I have a Handiquilter 16. You asked about threads....I have used several different types...all from Superior threads or SewThankful. I always used Bottom Line in the bobbin. I have used Sew Fine on the top...right now I'm trying to use Essential Pro from SewThankful. It worked OK in my last quilt AFTER a lot of adjusting. I've never used King Tut. I've bought so much of different kinds, I have hated to buy any more....especially since King TUT is so expensive. But, of course, it will be well worth it if it solves my problems.....which I am still trying to get going TODAY!!! UGH!!! Thanks for your help. Today, I have reviewed my video that came with my machine....gonna check it out to MAKE SURE I'm threaded correctly, etc....see if I've missed any little tidbits of helpful info.
