An idea came to me while reading UPPERCASE. I thought the subscription cards would be perfect for some postcard art. The card stock is heavy, and some of them have nice patterns on the back. I also found a flyer with a nice weight.
Sometimes I amaze even myself. LOL. I am kidding. I was trying to shove some pens back in their drawer but it was not going to close. Finally, a light bulb went off, and I tried stacking them in the opposite direction. Voilà! And DUH!
