Seriously. The title says it all. Clean your sewing machine with a pipe cleaner. It’s the best way that I have found to get lint out of a bobbin case. I give my bobbin case a quick swipe with my pipe cleaner every time I change the bobbin. Doesn’t take but a moment and it really gets the lint out! I’m serious you guys, go try it, and quit looking at me like I’m crazy! I mean, I know I might be crazy, but this pipe-cleaner-bobbin-case-thing isn’t an example of that!
