I really need to practice more. I usually do a lg meander stitch & am trying to stretch a little. I have had the on/off button on my Janome & also on my new Bernina but it always startles me when I use it. I runs much faster than when I use my foot pedal. I have been doing some sort of sewing for over 40 years & always used the foot/knee pedal so the button is something I need to practice more as well as using the open toe embroidery foot so I'm not turning the whole quilt to outline. These last few months have been a learning time for me.
