I'm voting for the printed fabric that is in position number 5 when you count down from the top of the stack toward the quilt top. It looks like it will match/or close enough to the boarder fabric of the top.

I'm also partial to the blue print.

I was thinking the blue fabric too! :mrgreen:

I vote with the majority in that the dark blue the 4th from the top is my choice. Very pretty colors. Do post photos when you have decided and have quilted it.
