Dotty Star borders

Over the weekend I chose a new layout for my nine Dotty Star blocks. The layout I posted last week felt like there was too much blue and not enough yellow. But this new one feels more sunny overall :)

The borders were cut and placed to correspond with the main color of each block. So now with the 3" border all around, my quilt top size is 60" x 60".

I purchased a black with white dots fabric last week for the binding, so now I've just got to find a backing and decide how to quilt it. I'm pretty set on sending it out to be quilted, but I'm not sure if I'll have her do an all-over pattern or something more custom. The quilt photographed with the pattern has the stars ditch-quilted with various circular motifs quilted in the background square spaces. Any suggestions for me?
