Sewing machine troubleshooting - bobbin thread bunching up

[Indadhanu]

wish i could have got my old machine fixed, I sewed PUL til the cows came home with that machine, never had an issue!!! I think I have it fixed though, by turning the tension right up (or... down... the book that came with it says two different things in one place it says turn it one way to increase the tension, and then later it says turn it the other way oh well, as long as it sews LOL).

With PUL make sure you don't have the shiny side under the foot. I haven't had a problem long as the shiny side is down
