I've cropped the image so you can see the edges of the painting. Once the painting is dry, I sand the edges and round the corners with a fine sandpaper, then float the panel on black foam core, leaving about 1/4" of foam core showing between the edge of the painting and the frame. A lot of my paintings are framed this way as it gives my work a more contemporary look.
