I sew on a Bernina 1008 (mechanical machine) and having trouble with invisible thread breaking inside the machine and the thread getting tighter and tighter as it feeds through the machine until it breaks. Anyone has a solution to this problem, let me know.
Just had the machine serviced last month.

You must go very, very, very slow with invisible thread. Try winding a bobin; it's even worse. It's not the machine.

Is it the top thread you are having the problem with? sounds like its just not passin through the tension discs. Try adjusting your tension right off, and perhaps if its a mechanical dial a little spray of silicone between them. That works for me. Or, even fix up a litl cloth that has been sprayed with silicone that teh thread can pass through, thus getting a coating of it on the way through....does that make sense?

I'm not an expert of invisible thread....but I believe it all about upper tension or the lack thereof.

I've heard it's easier to use regular thread in the bobbin and invisible in the top although I made something one time with it in both. I reduced the upper tension and did sew slowly. I kept telling myself I sewing slowly I was still sewing faster than hand sewing. It worked.

I used to have problems using the invisible thread. It would break no matter which tension I used. I would sort of unwind from the spool in between stopping and starting sewing. My machine has the thread unwind from the spool while in the horizontal(sideways)position. I turned the spool the verticle(upright) position and problem solved. I also use cotton thread on the bottom. Invisible thread on the bobbin caused problems and headaches

I've used invisible thread a lot, and as long as you do adjustments to the thread tension, you will be fine. Try it on scraps and fiddle with the tension until you like the look of the stitches. Also make sure the thread isn't getting hung up on something outside the machine... sometimes mine has gotten caught on the slit in the end of the thread spool where the thread was secured when it was purchased.

Dumb question here.....when/why do you use invisible thread?

Just curious......


Thanks!!!!!

I use it when I want the piecing to be the star, not the quilting.

I use invisable thread alot . A couple of things the top tension typically has to be adjusted way down. I use a very small needle 70/10 , this even works on thick batting. I use alot of invisable thread so I buy it on a cone , and using the thread holder stand really helps to get the tension relaxed before the tension discs. I had the most trouble using it on the machine spool pegs. It just did not want to unwind or theh spool move.
All brands of invisable thread are not made the same. Some have so much static in them it is nothing but frustrating. I have the best luck ( I need to make almost no adjustments in tension) is from Prim/dritz. This particular brand , is one that I can use on all of my different machines and have success. I get it from a catolog company called Home Sew.
Using invisable in the top and bobbin is really frustrating. I recomend only using it on the top.

I guess I'm the odd one (or lucky) as I've never had a problem using invisable thread. I don't even have to adjust the top tension. I don't use it in the bobbin as winding it stretches it too much, but I do sew slow. It could be the brand you are using. I don't know what brand I have. Sorry I can't be of any help :)
