Visual Stories, and some with words, on the Lessons from Life in a Picture Square. The square lets pictures breathe. It doesn't cramp the top and bottom, as do horizontal products, or squeeze them in on left and right as do vertical products.
On Greeting Cards you rotate the cards not the image, and it fits naturally on Shower Curtains, Phone Cases, Mugs, and Tote Bags as well You never have to rotate the picture!
