You can sure tell from all the comments on this thread that we are all struggling to get this motion from our head to our hands/machine!! I took a class and the one thing that stood out for me the most was to keep my hand and foot speed consistent. Sometimes my hands move the fabric too fast and as I 'forget to breathe', my foot gets heavier on the control. Hopefully it will all come in time. Next question: where on earth do we find the time to do all this practicing???
And thanks for the links suggested in this thread. Good luck to all of us.
