You never know when inspiration is going to strike, and sometimes an unused napkin at dinner provides the perfect place to sketch out your next brilliant idea. But you have to be careful, if your drawings are too crude you could end up with an 18-inch high model of Stonehenge like in Spinal Tap, or even worse, an eyesore like this. But if you keep a stack of these graph paper napkins on hand, not only will you be ready to wipe the barbecue sauce off your fingers, but you’ll also be able to produce super accurate schematic scale drawings wherever you are. A stack of just 12 of these napkins will unfortunately set you back $7 CDN, but at least they’re made from recycled paper.
