I made a few of these as a trial. Actually it took a lot of time to make them, believe it or not...
I used a 1" thick cedar deck board and cut 1/4" wide pieces from it. Then I cut the pieces at 7 1/2" long and used a jigsaw to cut the point on the end.
Each piece was hand-stamped and then I used a very fine Sharpie marker to fill in the letters.
These are for sale as are all the things I make - set of 5 for $15
