Susanne, at ATC is an Artist's Trading Card. They have to be 2 1/2" x 3 1/2" and can be vertical or horizontal. People make them and sometimes they trade them with other artists. They're really fun to make - just think of a very small layout. Start your document in those exact specifications, then treat it like a tiny layout. I have a link to some ready made ATC's that you might want to get. It's up in my credits: https://www.oscraps.com/shop/52-Inspirations-2023-No-43-by-Idgie-s-Heartsong.html - they're already the perfect size, then you just "decorate" it anyway you want. Hope this helps.
