Once upon a time, when A Muse Studio was still A Muse Artstamps, they introduced me to these little matchbook treats using their 4-bar notecards. If you would like a template, please email me. They are simple to make, and you can make four out of a 3.5"x10" piece of card stock. I used these for a make and take at a crop that I was invited to recently, and they were a big hit.
