How to do the polka?

Hey bloggy friends! Looking for a little help and inspiration today. I signed up for a polka dot charm swap from Craft Buds and just got my charms yesterday:

I already owned the whole bottom row, all but the left 3 on the middle row and 6 of the top row lol - apparently I really like polka dots.

My normal instinct is to keep them in their separate lines and not mix them (ta dots to themselves, metro circlse to themselves, etc.) - but that wasn't the point of joining this charm swap - I need to branch out and mix these babies up! SO what I am hoping to get from my lovely readers are some ideas on what to do with these. I have 4 of each of the 28 prints - so 112 5inch squares to work with. I have some other polka dots not from these lines that I could throw in if I need a few more. A quilt would be fun but I'm open to any suggestions really.

Thoughts? :)
