Step 10: You can get a small “fragile” cracklekit like the one shown in my Frida tutorial at your art or craft supply. It is two step process and you can follow the directions on the bottle….but basically you are going to cover your canvas with a thin layer of the “step 1” bottle, let it dry until it is clear and then repeat with the “step 2” bottle. As it dries, tiny hairline “crackle” will begin to form.  Then I spread another layer of brown glaze making sure to work it into the cracks and then wiped off the excess. You may want to do this several times until you achieve the “aging” effect you like.
