If you still have individual hexagon pieces, you might like to check out English paper piecing. It's a technique that makes accurate handpiecing really easy. I did it with about 1,500 hexagons this summer, it takes a bit of time but works really really well.
I picked it up here and there, but I bet someone here knows a good online link to the technique if you are interested.
Edit: Heh, crossposted. Links already posted! Don't you love this board. :)
