I completly understand. My father ordered me a pair of sewing shears when I was in 6th grade. We had to take HomeEc in 6th grade. My teacher had no idea that there were left handed shears.
Through the years I have learned to work my left hand into a right handed world.
I teach quilting classes now, and it is fun when you are working with a right-hander. They look at me funny. I just laugh. I did have 2 ladies that took my class that were lefties. I had to re-ajust how I had them cut the fabric. It was so fun.
