It took me almost a decade, but I finally got around to translating the visual aids I made for my mission. The black marks in the corners are registration marks for these to be cut out on a Silhouette Cameo (a fancy cutting machine). If you have a Silhouette, then links to download the Silhouette Studio files are at the bottom of this page. Otherwise, you can just use the images on this page and dust off the old X-Acto skills. Feel free to print, use, and share these!
