ACEO's are my newest obsession! They are small paintings, collages, photos that are collected and sold or traded. ACEO stands for Art Cards Editions and Originals. Mine are all original acrylic paintings. The only requirement is that they must be 2 1/2 inches x 3 1/2 inches. That's a SMALL painting. They look great in groups or matted and framed in a standard 4 x 6 or 5 x 7 frame. Some people put them in magnetized frames and decorate their refrigerators with them. Mine are for sale in my Etsy shop. Here are a couple of my recent ones.
