I certainly wouldn't change the rugs. I'm left handed for writing and at times ambidex - expecially with needlework. I think that depends on who taught me, if it was a lefty, I do it left handed, if a righty ? taught me, I do it right handed. My Dad taught me to have fun with it, he gave me a left handed pitcher, scissors, measuring cup, and other things. He also saw to it that I wasn't forced to write left handed and NO, I don't turn my hand upside down to write. Just be glad you are able to do so many things, no matter what hand you used.
