lief - easiest way. Lace one side, skipping every other hole in the hub, and lacing it to every 4th hole in the rim (Start with one of them laced right next to the valve hole). twist the hub, turn the wheel over and look at the other side. Notice on the hubs how the holes are off from the other side. Pick one to the side (working away from the valve hole, and lace it to right next to the spoke from the otherside in to the rim. Flip back to the first side. Stick all the spokes through the remaining holes first (i just find it's easier this way.). In the opposite direction of the first spokes, over two, under one. It will go right next to the last rim hole you laced to. Flip to the second side. Same thing, lace it to the only remaining side. Easy as pie.

Hope that made sense.
