The Great ATC Swap: Halloween Edition

The Great ATC Swap: Halloween Edition π
Make a tiny piece of Halloween art.
Send it to us.
Get someone else's tiny masterpiece back.
The Great ATC Swap is back for round threeβand this time we're getting spooky. Make one Halloween-themed ATC, mail it to us with a self-addressed stamped envelope, and we'll swap it with another maker's ATC and send theirs back to you.
The Two Big Rules
- It must be ATC size: 2.5β Γ 3.5β
- It must be Halloween themed
That's it creatively. You do not need to use Collage Soup imagery, although of course we love it when you do.
How to Swap
Put your ATC and a self-addressed stamped envelope inside an envelope and mail it to:
βοΈ Mail to:
Collage Soup
5669 Snell Ave, #284
San Jose, CA 95123
Please don't include anything else.
π Your entry must be postmarked by September 20, 2026
π¬ We'll mix up all the ATCs and mail your swap back by October 1, 2026
βοΈ One envelope = one entry
Don't Be a Stranger
We encourage you to put your name, website and/or social media information on the back of your ATC. That way, if your swap partner loves what you made, they can find you.
Everyone Can Play
The Great ATC Swap is open to all ages, so please keep your artwork appropriate for the whole community. No religion, sexuality, politics, violence or gore, please.
Spooky? Yes.
Creepy? Absolutely.
Bloody dismemberment? Let's skip it.
International Friends π
Yes, you can participate! Before mailing your ATC, please check the postal requirements for sending a stamped, self-addressed plain envelope from the United States back to your country. We'd hate to have your swap make it all the way here and then not be able to make its way home.
Ready?
Make your 2.5β Γ 3.5β Halloween creation, pop it in the mail, and then wait to see what another artist sends back.
Happy swapping!
