My quilting friend bought a 15000 last summer. She was a Bernina owner before that! but I have the 11000 so she asked for some help and let me come over to her studio and play with the 15000. I am in love and when I can afford one I will be buying one. Since your friend already has the 11000 she should not have a problem, without even looking at the manual I was able to get started sewing and embroidering!
