I used a template for these created by Sami that I found initially here on SCS. You can find all the info she shared here: http://www.splitcoaststampers.com/gallery/photo/2307002
They really make great storage for all of your A2 sized cards. Once you get the hang of it, I was making one every 15 minutes. For other photos of this project, you can visit my blog below. Thanks for looking!
