Good morning, I relate totally to the time with our grandchildren. Nothing else happens when I have them. Those moments go away so fast I want every one I can get while they are there. It takes me days to recover when they go home because I am worn out! I am glad you had a wonderful time.
mom-6, my sq9000 does that dance too. Makes me feel like I have been slapped in the face sometimes because it happens so fast! I am glad you mentioned it because I didn't cover that in my trouble log for Dee's friend.
Mary, I think the tread is a huge factor but haven't been able to isolate to the fiber of the thread. I am sewing with thread that is very linty (used to make uniforms). Now that I know not to pull the bobbin thread out of the thread path and to pay attention to the top thread wrapping around the spool stick I haven't had any problems. I do clean my feed dogs and bobbin case holder frequently. When they get linted up they get a stomach ache!
