My serger is about 14 years old but I would never part with it. Yesterday I pulled it out to do some alteration on a dress. I don't use it often but | wouldn't part with it. I did take two classes at the Quilt Shop on Sergers. That was the best thing I did. We made our own manual on how to do different techniques. We recorded our setting for each technique and they are still valid after all these years. I pull my manual often when I want to try something different. Once you learn how to use it you will not want to part with it.
