I am very left-handed and cut my fabric with the bulk of fabric to the right of me and the ruler is on the left and I then cut with my left hand on the left side. That might not be correct, but it is what works for me. I learned long time ago that it is a right handed world out there and I need to do what works for me. I attended country school (am not a young chicken) my first two years and my teacher tried to make me use my right hand - I started stuttering real bad. Mom took me to the doctor and he said - God created her to be born left handed so let her be. Within a week, I no longer stuttered.
