Ok, I went to a Sewing Social last night planning to do some thread play free motion work on a Christmas wall hanging. I got all my stuff out, threaded my Pfaff 360 - which is the best FM machine out there in my opinion! I started to sew . . . . and had a thread mess. I had to rip out what I had sewn. Tried again after checking the thread path - again a thread mess! I took out the bobbin case. The bobbin case was missing the tiny screw that sets the tension! Somehow that screw had fallen out since I used that machine last month at the same social doing FM work! What a weird thing to happen! I have never had the screw just disappear from a bobbin case! I fixed it this morning robbing the screw off a BC that doesn't go to any of my machines . . . it came with some attachments I bought on e-bay. I guess from now on, I will take a back up machine!
