My Allie's Hourglass quilt top

A few days ago I thought I was finished with this quilt top but I didn't feel like it was large enough. 

I've added a row in length and then put a border all the way around using the little 9 patches. 

This quilt is now 75x66.

The scrap bin is now 1/2 empty so that's a win! I made this quilt almost entirely from stash and scraps.. Except for the white + print.

Now, staying with the theme "use up my stash", I have two backing possibilities...yellow dot or mini print. 

Which do you think looks best?
