Right handed use right foot when I use a pedal. Because I have restless leg syndrome I find my legs get really tired and the more stress I put on them (i.e. sewing or quilting a lot) the worse they are. About a year ago I unplugged my Janome sewing machines from the foot pedals (and now I am not sure where either pedal is- LOL) and I strictly use the start and stop button. People say you aren't as accurate, but I have not found that to be the case. I have slowed my sewing down to be more accurate and it has helped greatly with putting blocks together and has saved on my legs hurting so much, because when I sew on Saturdays in particular, we can sew from 10 a.m. to 11 p.m. with dinner breaks. If you are having surgery and can sew on your machine without having to use a foot pedal - slow the machine down and try sewing on it now without the pedal. I do it all the time and has been wonderful. Good luck with your surgery "tomanycats" and if you have any questions, do not hesitate to pm me.
