Mix & Match Dining Chairs

I recently picked up a solid wood, Ethan Allen kitchen table off Craigslist - score! It needs a little elbow grease: sanding, staining, painting - but it's the perfect size for our modest kitchen and will provide the additional place settings we desperately need. And for $40, how could I turn it down?! 

As for the seating, that's still to be determined, but I'm totally loving the look of mis-matched, yet cohesive dining chairs. Here are a few styles I've been eyeing.

Love the pops of turquoise here!
