What's an ACEO?
ACEO stands for Art Cards Editions and Originals. An ACEO is always 2.5" x 3.5". The size of a standard sports trading card. This is the ONLY rule in the ACEO world. They can be made out of any medium: paint, plastic, collage, colored pencil, metal..pretty much anything.
Here are a few ACEOs I found on etsy:
1. Blue Ox ACEO original by vusova
2. Love is cream, ACEO PRINT by holli
3.Twin Dolls - original ACEO by Ulaa
4. Neema - Original mixed media art card - ACEO by carambatack
I think I'm gonna make a few ACEOs.
