I have used Sulky and this is my suggestion also; a topstitch 80/12 is what I use. I also use bobbin thread when using Sulky.

I had the same problem. Now use Signature, Superior, Aurifil, Wonderfil, Mettler, Madiera,and Gutermann and all of them perform brilliantly. Give them a go.

Sulky threads are generally considered embroidery machine threads. I would suggest finding a thread specifically used for quilting. There are many good ones out there, and you are bound to find one the right color. I love YLI variegated threads for machine quilting.

I don't have an embroidery machine, but that was my understanding. I have never even looked at Sulky for that reason. Will be following because they do have beautiful colors and sheen.

Switch to a polyester..it's stronger. I like what Leah Day uses--Isaacord 40 wt. or polyneon Madeira. It doesn't break when FMQ...well...hardly ever...

Google dealing with difficult threads, there are several articles on this problem with some very interesting posts. I was having the same problem with silky doing decorative stitching and found some solutions. Good luck, I know first hand how frustrating this can be.

Top stitch needle is a must 90/14 or 100/16.....high quality, long staple cotton thread for FMQ has worked for me...

I was going to pick some up then saw it was for machine embroidery. That settled that. I'm a Coats and Clark gal and have no problem with my thread unless it's user error.

My vintage Commander is strictly a Coats and Clark. My Brother didn't care, but I got tired of chasing that plastic thing while it jumped around the table so I've gone vintage. Them old gals don't move.

i use connecting threads cotton 40wt for piecing and have never had a problem. i also use it to fmq on my brother with no problem. right now i'm using a 50wt prewound bobbin (who knows who made the thread?) and my usual 40wt top thread. my brother sews with anything and never has had a problem so perhaps that makes it a less than strong endorsement for the thread. i have never had a picky machine, knock wood! lol. even the metallic thread gets along well, no special care taken or needed. (so far). i do really like the connecting threads thread for the colors, strength and nice stitches. hope you find a thread that you and your machine agree upon. 8-):thumbup:
