Hi! Welcome! Super glad to have you here. Turns out, you're in the right spot for a cracked paint tutorial. Dolce Sentire, one of Cookie Connection's regular contributors, just posted a tutorial here on the topic: http://cookieconnection.juliau...alentine-cookie-boat (She shows how to apply the crackle effect to the boat hull, and provides several great general tips about the technique as well.) Have fun!
