I love looking at ATCs. I’ve made a couple.
It’s really fun! For those who don’t know, an ATC is an Artist Trading Card.
They measure 2.5″ by 3.5 inches. You decorate them in your favorite medium.
Can be collage, painting, chalk, a little book- that folds out, anything.
For Etsy sellers an ATC can be a picture of your product with info on the back- a more fun version of a business card!
Do a search online to see the wide array of ATCs.
