RED!!!

the red is lovely and the block is beautiful, so delicate looking :D

I like the Red - ties in very well with the rest of your blocks

I like the red. It stands out more.

Do you any of the lighter blue, like you used in the blocks? That might give the sashing a softer look, just a thought. Love your blocks too, great job!

Gorgeous blocks - I think the white makes them stand out.

I vote the red

I like the white and the red. The white gives it more of a light summer or spring feel to it. The red is also nice, it pulls out the red in the quilt block.

There's already a lot of blue in the block, I wouldn't use blue and the black doesn't blend with the block at all.

I think your quilt squares are very pretty.

I think I would go red or white.

I like the red the best also. Lovely blocks.
