LGJARN52, I can relate to a day like that but I can also say the quilt I was having so much trouble with is now completely done and ready to be gifted out once I get his parents' quilt done which I haven't even started and it's a queen size quilt.
The machine you are using, it is a quilting machine or a regular sewing machine? As for the thread, I had this breakage issue before and read about putting the thread into the freezer over night as that will put moisture back into it. Of course that didn't work on my Aurifil thread and I gave it away for someone else to try it on their machine as not all threads work on every machine. My Innova hated the sample thread that came with it so I put that thread over to piece with Most of my threads are at least 10 years old, hanging on the wall but I now have curtains over them to keep them from getting dusty at least. My machine room does get quite dry in the winter time too so that doesn't help the thread.
Sure hope you figure out your issues and if nothing else. Just walk away from the project for maybe a day and then come back as things might start to work again for you.
The other day I lost my stylus pen to my robotic tablet so had to come up with something to use to finish the quilt. Found I have a smaller stylus that came with my embroidery machine so used it. When I went to clean the machine, wheels and rails, then I found my original stylus laying on the backside of the frame. I was just about ready to order a new one but I knew if I did, I'd eventually find my stylus and so I did but without ordering a new one. Good luck with your quilt.
