Expanding my game board (8' by 4')

I have been getting my prints done and working on my gameboard. Still have to print more out and then paint, flock, and apply sealer to my hexes. Does anyone have any great suggestions for transporting the hexes after all this work? Several of the local game hobby shops love this terrain when I bring it in, but just tossing them in a cardboard box for transportaion is less than ideal.
