Double slice layer cake flimsy

I might actually get a baby quilt finished in time for the baby's birth (rather than it's fifth birthday!).

This flimsy is made using the Double Slice Layer Cake pattern and ABC Menagerie by Moda.  It makes for a very lively quilt top.  I was going to back it with the remaining blocks but I think that'll end up looking too busy, so my next (very unpleasant (!)) job is to go to the LQS which stocks Moda fabrics and find something suitable for the backing and binding.
