I spray-glued the hexies down, and I'll applique them on before I build the sandwich and quilt the whole thing. I'm tempted to add 7 hexies to the back, too, just for a little extra punch of fun. :o)
I used 52 hexies that I've gotten from being a part of the Hexagon Swap on Flickr. I really loved having the variety to be able to choose enough hexies that I loved and go well together.
