I watched it twice so far as I really like her calm approach to teaching. Got mine when it was on sale.

Nanny, Sew4Less has generic walking feet. You will just have to know if your shank is long or short.

I also took her Craftsy class. I loved it, but I realized while I was watching that all the quilts she quilted on were small and easy to move through the DSM throat and that I probably would have a hard time moving a larger quilt through the throat of my DSM.

I took the class and used my walking foot on the border of a small quilt. I used a stencil to mark the quilt and then stitched away. I really like the class and will use her tips again. I don't know the name of the design I used but it was lines criss crossing. I used my Viking Ruby and a purchased walking foot for this.
