I think I would use a white sashing, but I agree about auditioning various choices. this will be a very lively, joyful quilt!

I like white - or none at all

I really like your scrappy sampler.....how about some black and white dots for your sashings. I made this very scrappy quilt using crumbs and I didn't know what I was going to use for my sashings either then just for the fun of it I put these dots nest to my blocks and I loved it so went with it. Even red and white dots would also look nice with your blocks.

I like the white sashing -- floating those beautiful blocks.

Any color would work great since you have so many. Very pretty.

My vote: white.

Love your blocks...so vibrant and fun! Can't wait to see the finished quilt.

I like the idea of white or actually any one of the colors that you want to use in a particular room - a yellow or blue or even a bright green or orange. I personally think black would bring the blocks down to much. It's going to be very pretty.

try a teal or yellow.

love your scrappy crazy quilt.

White would make your blocks float. If black is a bit too stark for your purpose how about a dark to navy blue. It would kind of draw out the blues in your blocks and draw it together whereas the black would set up very strong dividing lines. Just a thought.
