I have a serger that is about 20yrs old that I use to use for making clothes. I havent used if for almost as many yrs. I've been thinking lately about getting back into it but not sure if I have the instructions to the old simplicity or not and if it still works; it used to. I have a friend who serges around her quilt tops once they are completd until she has time to quilt them. She can see in a moment is they are finished tops or not and it protects them from raveling while they are waiting to be finished.
