Sometimes I get so involved in quilting I forget to clean. Once I had so much lint under the cover that it pushed it up. Never again.
I had my old Pfaff do that several years ago. I didn't know that I needed to clean under the throat plate and one day it was lifted up and wouldn't sit right and I was baffled at why. Until I figured out how to remove the throat plate. I almost had a blanket under there. I am much better at cleaning up around the bobbin now with my Bernina. I give it a quick swipe after each bobbin and a really good brushing out every 5 or 6.
