OK- sorry for the cheesy song lyrics but FMQ and are are getting back together.
First off, THANK YOU for the TONS of great advice, suggestions, and help. I ♥ you and can't thank you enough for your patience and your help!
So, I changed threads- yes I loved, loved the look of the variegated Aurifil I was using (the 40 wt) but my machine obviously did not.
(BTW, I have a Pfaff Classic Style Fashion 2023. It's about 4 years old and was my mom's and she bought it for garment sewing, not quilting but it does have an integrated walking foot and the manual has a section on FMQ.)
So, I cleaned everything again and this time put in my Aurifil 50 wt and a new needle and am going a bit more slowly and so far, so good. I've spent some time on some practice quilt sandwiches and then jumped over to the big quilt.
While I need a lot of practice on maneuvering the quilt, at least at this point my thread is not breaking or getting those awful bird's nests on the back.
Soooooo, I'm cautiously optimistic.
Pictures soon- hubs has the camera with him so I don't have any to show you at the moment but I am going to jump back in during naptime and see if my luck will hold.
Seriously though y'all, thanks for all the love, the help, the comments and the support!
