One thing I learned from her at a class is soak thread, poly or cotton in mineral oil, take it out and let sit on paper towels, wipe off, and use. It makes a world of difference. Good for the machine too. I do this with all new spools of thread. I keep a plastic covered container with mineral oil and roll the spools in it. it will not stain or harm fabric. No oil puddles or anything like that. She gave so many tips explained how the tips worked for machine and long arm. Everyone was taking notes and saying Wow.
