I had wanted to make it like a rainbow by pairing the ones with a red image next to a red piece of sashing,etc. Similar to this one from jarobichaux's flickr page (Only not quite as awesome as I would use solids, just ROYGBIV and B&W):
I did not want to have the solid squares as large as the I-Spy squares, was thinking maybe 1 inch sewn (1.5 inch cut).
But then I realized that it wouldn't match up if all the blocks weren't the same size. And I have SO MANY blocks it would make a HUGE quilt.
I could smoosh them all together like iris b2007 did here, but I doubt my eye for it (though the more I look at it the more I like it.)

So then I though about doing all one color sashing like this one from the Rice Family's flickr page:

Should I give up on the rainbow and do all the same color sashing? Or should I use fewer squares saving the rest for another quilt? Or do you have a third idea?
