What Airsporter said. Checkering tools ain't cheap, and it takes better eyes and more patience than I have to to learn. There is no way you can start right in and do a decent job on the first try.
If you do want to learn, the place to start is recutting checkering that is already on junk stocks. Touching up a ding in existing checkering ain't too hard and is about as far as I ever got. The next step is checkering over that gawdawful stamped checkering that was used in the '60s. I've seen a couple of nice jobs done of that and was told that it was not hard because the layout was already stamped into the wood.
