Small things are charming. I've been making artist's trading cards for over 10 years and they still feel new. The standard marketing line is "make it miniature or put it on a stick and you've got a top seller."
I'm working on an ATC gallery for NAChattin.com and I keep getting distracted by designs I want to try again or ideas that would be fun to teach. One of my latest favorite techniques with ATCs is to adhere them to a card base and make an "instant" greeting card.
I had the pleasure of exchanging trading cards in a swap last June with some amazing artists including Pam Grant. Here are two greeting cards I made with her Artist Trading Cards.
She used collage images of photos from the 1920s and jewel embellishments to create these treasures. I added a bit of ribbon or string and a print background card base from DCWV. Oh joy.
