Over the years, I’ve swiped a few items from my wife’s makeup kit in the service of my craft. I’m particularly fond of lipstick, which I keep in my toolbox for marking lock mortise locations in door jambs. For example, after installing a deadbolt in a door and attaching the door stop, I wipe the lipstick (I prefer “Midnight Passion”) across the end of the bolt. I retract it, close the door, and then throw the bolt, letting it kiss the door jamb to indicate the best placement for the bolt mortise and striker plate.
