Connecting Card Pockets (ATCs)

Here you will learn how to fold a modular/practical model of my own design: "Connecting Card Pockets". Since it's an origami quilt, you can choose where to connect each unit and how many to connect. And, thanks to their corner pockets, you can attach a 3.5'' x 2.5'' card on each of its sides. It's perfect for displaying trading cards, including ATCs! Attach 10 cards to a strip of 5 x 1 units, 18 to a 3 x 3 matrix, 56 to a 4 x 7 matrix, and so on. What's better than using origami to organize and showcase your collection?
