Sashing colour suggestion

Hi all

I'm planning to make a quilt for my little guy, probably stacked coins, using David Miller's robots fabrics (these have a yellowy-white background and moderately bright yellows, oranges and reds and lighter blues), plus some funky bright green and deep red fabrics from my stash.  My problem is I have NO idea what colour to sash these with.  it's for a 5 year old, so I don't want to use white or off-white. 

Any suggestions?  I'll probably use Kona cotton (because it's cheaper).

I'd have to check the fabric you mentioned, but French blue popped into my head.  Blue and yellow make such a happy combo!

I'd go with blue too.  Nice choice of fabric, I love that line.

I agree that the blue sounds like the best choice.  Although depending upon your fabrics an orange or a red could also be fun.

I've been on a green kick recently and it sounds like that would work beautifully too - maybe something less bright (but in the family) of what is in the print.
