The colors do look great together. Those cutting boards are just too pretty to use. Better cut a keyhole slot on the back so they can be hung like a picture.
Here is a link to the tutorial that I followed "http://lumberjocks.com/Tikka/blog/1878". As far as the glue up goes, I dry fitted the entire board to make sure there were no gaps, then glued the whole thing all at once, one piece at a time. I used titebond III. Lots of sanding came afterwards!! I guess a planer would make it easier, but I don't own one yet. Except for routing the top edges, I did these boards by tablesaw only. Hope this helps. Thanks
