I'm trying to FMQ using sulky invisible 100% polyester thread (both on top & bottom), and my bobbin thread keeps breaking. Grrrrrrr.
I've got my upper tension on 5, using a 14/90 needle......
Any one have any hints?
This is my first time trying the invisible, as no solid color will match, (grandson's birthday quilt of big yellow appliqued smiley faces, on blue backgrounds - his design!) and I'm about ready to toss it all out the window!
