I think being ambi means you you everything with either hand - I do somethings right handed - cause that is how I was taught many moon ago - and there were not left handed things available - at least that we could afford. I mostly do detail things with my left and strength things with my right - but condier myself a lefty - also I am left eyed so if I want to get something 'right-on' I need to look at it with my LEFT eye - like 1/4" seams - if I look on the left side - I get it measured correctly - wierd - but I'm just ME ! I've been a lefty and strong-willed forever !
