2.5" x 3.5" Canvas Card
I've always liked this Monet-like ACEO and now it is in a beautiful soft white mat and packaged in an archival bag, it looks stunning. These make wonderful house-warming or hostess gifts and are perfectly priced to give to teachers as well. Who wouldn't love to receive a pretty little miniature painting.
You are saved the worry of framing because the mat is a standard frame size available almost anywhere in many colors and styles. That way the person receiving the gift can purchase one which suits their decor right off the rack.
