That's great advice from Pete Roszyk. Here's one additional tidbit.

You can't make it round like a stripper (;-) but you can make the glue lines almost disappear. You saved the wood flour from your sander, right? If not, sand some scraps until you have some more. Mix up some epoxy, add the flour a little bit at a time, and eventually you will have a perfect color match. If you go too far, use it someplace that doesn't show and start over. The resin darkens the natural wood color, but at some point there will be an almost perfect match. If you use that for filling the outside seams and butt joints, it looks like a continuous piece of wood.
