Since I don't have a router inlay kit, but still needed to make a few dutchman style patches for a table i made, I went "old school'. I made a patch to fit the area I needed to cover from some 1/8" thick scraps of the same wood as the top. I then marked out where the patch would be on the top with a ball-point pen. I then used a sharp chisel, and by counting the number of "hits" at each spot ( four, I think was the number) I went around the marked out area. Once all of the lines had been "hit", I then used the chisel, bevel down, to pop the waste out. By test fitting the patch for a tight fit, I could pare out just enough for the fit. Some glue, and a few taps from a hammer, patch was in place. After the glue was dry, a hand plane smoothed thing out. Now, the wood in those patches doesn't HAVE to match the wood it sits in, one could always highlight those patches with some showy design. The patches for that TV Table had to cover old carriage bolt holes, as the wood ( redwood) USED to be a Pic-nic table. Reclaim, re-use, and recycle.
