hope everyone can help. do you use compressed air when cleaning your sergers and sewing machines. i realize oiling and new needles are important. the dust bunnies are huge when sewing flannel. i have heard pros and cons. as i have seen many of your sewing rooms and notice there are several machines in each, i am sure you know how to keep them clean and running in tip top shape, also the many quilts are beautiful and the machines must be working well. thank you in advance for your comments.
