When growing up we never had left handed scissors. So I learned to cut fabric with my right hand. It is about the only thing that I do right handed. When I cut with a rotary cutter, I switch the blade and use my left hand. Sometimes I do get frustrated with rulers. The measurements are always on the wrong side or backwards. Just the joys of living in a right handed world :D
Had a left handed friend tell me that everyone is born left handed. People only become right handed when they commit their first sin. Sounds like a good one to me!
