Fat fingers, skinny fingers, it doesn't matter. If someone told you it would be hard to play because of your fingers, they're an idiot. Any one can play as long as they have each set of 5 attached. I've got normal fingers, a friend of mine has got HUGE fingers (like rocks attached to his hand) another friend of mine has bone-like crooked old woman fingers, it really doesn't matter what your finger looks like, it's how you use 'em. Practice and you'll be fine.
