I just thoroughly cleaned my Singer 301A yesterday, after a couple months of not being cleaned and only had about a 1/4 of the lint that she did. LOL. Of course, I do not sew 8 hours a day, but do sew a lot. I really enjoy the videos they share. After watching the spring cleaning, I watched the Jacobs Ladder....will definetely be doing that one very soon. Thanks for sharing.
