Some of your most brilliant ideas have probably come to you after you’ve had a couple glasses of vino. When you’re out, those ideas get quickly transcribed onto bar napkins that proceed to get wet and leave your plans to create a working time machine lost forever. This sketchbook from Baum-kuchen serves as a repository for those genius napkin sketches. The untreated leather sketchbook stores your napkin doodles, a fine-tip Sharpie, and comes with 10 napkins to get your creative juices flowing. Now, when you wake up the morning after a bender, your grand ideas won’t look like a woman’s mascara after watching Marley & Me.
