I like ESQMommy's idea, when I first looked at them I thought a cream or a yellow... then bring your other colors in as a border... just my thoughts.

I love your blocks.

I love the idea of the blue, but I think the blue in the photos is too bright. Do you have any fabric the same color of blue that is in the background or the edges of the blocks? If you do, I think that would compliment very well. I also like the idea of cream/yellow. If you don't have any of those, I think the green is the best choice of all. I, too, like the idea of using the other colors in the borders. I think doing stripes might add to the busy-ness of the blocks, instead of toning them down a little bit.
I love the way you put the blocks together. And what cute fabric to start with!!! Good job! :D

I agree that the blue and red seem to draw your eyes away from the blocks. I like all the colors, but I think I would go with the green and use the other colors for borders! Your blocks are great by the way!

Red makes it pop!

I love all three. This is tough!!

Maybe sash with one, and borders of the other two.

Great job! Can't wait to see more!

The green in definitely my favorite.

did you try a cream color/

They all look good but the green caught my eye and made the quilt quieter. :D JMHO

I like red first then green, not too much the blue for me. But I agree with esqmommy, try cream/yellow/gold and see how that does. Good luck with whatever you choose. Can't wait to see the pictures :) :)

Really love the red makes it pop rirht out :D
