If you've never made an ATC here's some information about them:
ATCs are small works of art that can be traded with other artists. They can be fun to make when you don't have much time or space. They are also useful as little reminders of messages you wish to carry with you, perhaps in your handbag, backpack or in the car. They are also nice to give to others as little random acts of kindness.
- The dimensions of an Artist Trading Card are 2.5” x 3.5” or 64 x 89 mm
- ATCs can be made from: playing cards, flashcards, cardboard, mat board, cold press watercolor paper, or you can also buy ATC packs from art suppliers.
- Materials to use for your ATC can range from collage, mixed media, stamping, drawing, painting, photographs and more!
- On the back of each ATC you may like to write a message to yourself or to the person who receives the card, and the date ATC was created.
