Re the magnetic seam guide I have read that you should not use on a machine that has electronics. Just FYI. I sure wish I could find one that works well on my Pfaff. Have tried post it notes,command strips, tape etc but still can't get a scant quarter inch because I can't get close enough to the feed dogs with the quarter inch foot on it. Still trying. The one on Nancys Notions has been unavailable since way before Christmas! If you have another idea please post!
