I am left-handed also and use the tools like right-handed folks do for most things. I do use the rotary cutter with my left hand though. My mother was forced to change to her right hand for writing and her handwriting was miserable. She took me to school and DARED the teacher to try to change my handwriting. I do not write upside down or drag my hand through what I have just written. However, open heart surgery changed all that when my left hand was strapped tightly for 5 days. The nerves were damaged in my left hand and I cannot write well, nor can I type on the computer well now. Therapy hasn't helped.
