Julie Schneider and Bre Pettis recently created this awesome tutorial for Etsy on how to create Valentines with Gocco Printing. Everything you need to get started comes in a kit. Your designs have to have carbon in them, something you can get from most standard printers or through drawings made with the included Gocco pen. Once you create a screen of your image you can make tons of copies to pass out to friends or even sell in your Etsy shop.
