Hear, Hear!
Whenever I have taken a class or workshop the reaction is the same "oh, dear, you're left-handed". It's not catchy!
I use the Olfa erganomic cutter and have no problem with it. Many tools now are made either ambidextrious or in right / left handed versions so I don't really have a problem.
It is usually funny when the girls and I get togehter to sew; after I use the ironing board the next person starts to iron left handed and suddenly feels like "something isn't right". And I giggle every time!
