Domino marking tip

[art stratemeyer]

As I go through lots of scrap material playing around with the new toy, quickly found on thing. If you are doing a lot of edge mating with many pieces where one mortise is cut "tight" and the rest loose .. it's easy ( at least it was for me ) to lose track of which one you want to cut tight.  I simply drew circles through the marking lines for the ones to be cut tight
