I like the background fabric the pink almost looks like white from a distance.

How about a narrow pink flange between the white border and the printed binding? The print sets off the delicacy of the rest of the quilt.
Lovely quilting, by the way.

Backing vote here. Looks great.

Print for my taste too. It makes the pinwheels stand out a bit better than the pink.

Ditto Print!

The pink is soft and delicate, but, I vote for the print as it brings out the pinwheels. NICE QUILT:)

I like them both ,but I think the pink would continue the theme

I too like the print. Very cute.

I vote for the pink. Sets off the blocks.
