I just started a quilt this morning with Sulky polyester, it's so soft and fine, like baby hair! hard to thread because it's so hard to see and you can't feel it at all, so far I love it.

I have 3 spools of invisible thread that I bought with the intension of using it for quilting. I tried it and had nothing but problems. I just changed my mind and went with something else. Problem solved.

The brand of thread can make an enormous difference. The only type I have sewed with on my Bernina is YLI brand, which I think is .003mm thick (about same thickness as a strand of fine hair). This type of thread has more stretch than regular thread, so it is necessary to loosen the top tension. When winding a bobbin, use only a metal bobbin (plastic bobbins) can distort, wind slowly to prevent stretching, and underfill the bobbin. With all of this, I can use YLI invisible thread in both top and bobbin without problems.

I ws told never to put invisible thread in the bobbin but I too have had trouble with thread breaking. I will try the 'go slow' part. That might be my problem. Many times I wish I could have used the invisible thread and then remembered all the trouble I've had. I even used the superior quality invisible thread to no avail. Thanks for all of your advice!

I use invisible thread a great deal. I really have very little problems with it. My dealer instructed me to not use it in the bobbin. I have a Viking 630. I have read that hand winding is best because it will not stretch the thread as machine winding does. Also, if you are having trouble threading the needle because you can't see the thread, I often run a magic marker over the end. That you can see. Works for me.

Funny story (funny now, not then) about using invisible thread in the bobbin the first time I tried it. You know how sometimes when you wind bobbins, if you're not careful, the thread will start winding around the bobbin-winder shaft instead of on the bobbin? Yup. By the time I realized what was happening, I had a bunch of that invisible thread wound around that shaft. It was so tightly wound that I spent a couple of hours cutting and unwrapping thread from the machine. I never tried to use it in the bobbin again.

I've used invisible thread in my Bernina's with no problems. I used the Sulky and it's the only Sulky my machines like. I used it in top and bobbin for sewing free standing lace together.

I went to a class on thread that was put on by Babylock. The rep said that invisible thread has to be rested. I put mine in the back of my machine in a small what use to be an ashtray, and then thread it through the machine. I have very little breakage this way. Also when it does break you should go at least a foot away from the break and cut that off, because the thread is damaged that far up. Hope this makes sense, because it does work.

What kind of invisible thread do you use? I use Invisifil and it is wonderful. It is the same size as regulaer thread (not fine like baby hair) and I fill the bobbin with it the same as regular thread. I've never had a problem with it. I used Invisifil to FMQ this table topper.

(Fingers crossed here - this is the first time I have tried to post a picture. Here goes.........)

I don't use it in the bobbin, and I put the spool in a heavy coffee cup behind the sewing machine. I still don't understand why this works, but it does.
