A deck of playing cards can be very useful around the woodshop. One of my favorite uses is for shimming my dado set. I drill a 5/8-in. hole in the center of several cards and keep them with my dado set so they’re ready when I need them. Playing cards are also handy as disposable glue spreaders and for leveling the feet on my rolling workbench. Waiting for a finish to dry? How about a game of solitaire?!
