I have that machine but never sewed on it. I collect little machines. I feel at 10 years old she is ready for a grown up machine. I would cut up some 4" squares for one quilt, maybe 6" squares for another one. Then I would cut up an Ohio star and show her how to do the triangles. These are fun projects. If she is into dolls, cut some smaller pieces like 2" squares. You are starting something that she will have for the rest of her life.
