I think the real solution is practice
Well, yes and no. Practice will definitely help, but the foot itself will never give power in an even way. Part of the problem is that when you're trying to drive the machine at a slow speed, you're not getting full power to the motor. An 'electronic' foot always delivers full power to the motor even at low speeds. You may find that you'll have to help the the machine along with your hand on the fly wheel to get the needle to penetrate the fabric when stitching at slower speeds.


You tell it you want a buttonhole, then place the button up against the screen and the machine calculates the buttonhole dimensions automatically. . . scary.
I've taught at a lot of sewing shows and I've seen some fantastic things that home sewing machines can do, but when I saw that feature come out I knew that someday, I'd have one of those.....that was 3yrs ago. Unfortunately, when a new machine costs more than my 3yr old Mazda.....Seriously, some machines will run over $6000!
