I would suggest that you find out where she got it because they are supposed to come with free lessons on how to use it. My mother bought one and didn't like it, was used to her old Singer and didn't want to learn how to use the Phaff. After she died, I took it in to the sewing center where she bought it and they have offered to give me the free lessons instead since my mother never took advantage of it. And this was three years later!
It's a very good machine and if you sew at all, you will love it once you learn how to use it. It's worth investigating anyway...
