Picturing This: One of my first sales on Etsy was a customer requesting an ACEO of an image. Actually, I don't think she was for sure, but I got the idea that I should create an ACEO of the image as an offering, and I might have a sale. I did a little internet research and made my own way of creating ACEOs.
ACEOs are minature art, 2.5" by 3.5", that artists are "trading" and collecting like they would collect art (If we had the walls and money). They are a nice way to check out someone's art skills without breaking the bank. They usually range in price between $3 and $8. The images are exactly the size of baseball cards, so they fit in baseball card sleeves for storing.
