Mairead unveiled the models of violins in her line today!
The violins Mairead chose for her line reflect the warm, sweet tone she prefers.
Here's some videos of Mairead explaining the violin models and also the bows she's using with each model.

... or at least play violins like the ones Mairead plays 
I'm excited and I don't even play violin! Lol!
I do think it would be pretty funny though for me to attempt to play The Butterfly with a Butterfly, twirling my clumsy self about the room, kicking and toppling things over excitedly.
