I am about as left handed as a person can be; but I've never had a problem with any machine but my featherweight. The needle threads from right to left and it took me a long time to learn to thread it with my right hand. All other machines have seemed perfect to me as a leftie. Now that I can thread the featherweight, I love that machine. I do use a left handed rotary cutter; but I have always cut with right handed scissors in my left hand. I had done that for so long that left handed scissors do not feel comfortable.
