Total frustration. I'm quilting with my new Pfaff Creative Sensation, and I keep getting a nest of thread underneath. I'm using a decorative stitch that I designed, using the design feature on the machine. I've tried all the usual things: rethread, clean out lint, make sure the bobbin is in correctly, change tension - even though this miracle machine is SUPPOSED to set tension correctly. I'm using Superior Rainbow thread on top. I WAS using Superior Bottom Line in the bobbin. Then I changed to Sulky Rayon 40 on the bottom. Didn't help. I'd rather not use the Rainbow on the bottom.
I think Dr. Bob of Signature Thread has a Thread Tutorial somewhere in You Tube, but I don't know how to search on You Tube.
I suspect someone on the board can help.
