Hi Kate. Welcome to Mudcat.

I know of several left-handed fiddlers from Cape Breton/the Maritimes who are sinister as well. Several of them play "right handed" ie a regularly strung fiddle, with the bow in the right hand. Some of them play the fiddle strung the opposite way. A few of them, most notable is Ashley MacIsaac, who plays a fiddle strung right handed but bows with his left hand.

I'm not going to suggest that it was easy for him, but it could be that it was easier than bowing with the right hand. Apparently they have to do everything the opposite of what they see/hear. But it DOES work. It allows them to play any fiddle wherever they might be in case of problems.

Hope that helps.
