I collect the same info, but I kept misplacing the cards. I finally came to the conclusion for me a 3 ring binder was the way to go. I find it surprising on how much time and money is spent on each machine. Each SM has her own page, her name matches the previous owner's name or town where she came from. I have been having a hard time cleaning, repairing machines and trying to get quilting done. How do you gals do it??
