This sounds interesting. I use my walking foot and when free-motion quilting I use a built-in regulator that bernina's come with.
I think you are really getting some good information there. I hope you show and tell us the results soon. I haven't tried the built-in quilting blocks yet. But, someday I will. It is tied to the embroidery unit designs. A built-in program.
What type of machine are you using?
