Sophie and I have worked together for a bit more than a year. I had hired her as an instructor at the other sewing studio and when I left she followed me. Sophie is also self taught and it shows in her ability to take on rather ambitious projects with little worry they may not succeed. She has a very much "Make it work" attitude when it comes to sewing. Making it work is an excellent skill to have when you teach sewing classes, especially to kids. Sophie has much better design aesthetic than I do and most of the design elements you see in the studio are her doing. Our skills compliment each other and we make a good team.
Sophie sews at home on the Bernina 530 which I gave her as a gift when it was clear she was due for a machine upgrade. The knee control on this machine is for sewing, not for lifting the foot.
