Thanks guys. You should have seen the 2x4 I started with, it was a really old dingy board. I used a 2.25" hole saw to punch out the holes. Sanded off the top and bottom to get the them to match the interior of the wood. I
threw them on a lathe to smooth them out, taper the tops and sand them silky smooth. Finished it up with a layer of clear coat I had laying around. I will probably add one or two more layers of clear coat for added protection then buff them up some. I thought about staining them, but I really liked the wavy marbling of this wood and didn't want to cover it up. All in all I am happy with the way they came out, especially since I considered them to be proof of concepts.
If I ever make any more, I may try to start with better looking stock wood.
