Select an image, theme or design to draw, or project, onto the foam core board. If you are drawing your image, lay the foam core board onto a flat surface. For projected images, place the foam core board in front of a projector. Place an image onto the projector, and project the image onto the foam core board. Trace the projected image directly onto the foam core board. For projected images, repeat this process on another sheet of foam board.
Cut away the outer edges of the image with a utility knife. Make clean, smooth cuts.
To reproduce hand-drawn images, lay the image on top of another sheet of foam core board. Carefully trace around the cut image. Once the image is completely traced, remove the upper image from the bottom image.
Cut the duplicate image out using the utility knife. Use a slow and careful technique.
Place a pencil mark from the top center of the first image to the middle of the first image. Use the utility knife to cut away this section. Make sure that you remove enough foam board so that the other section of foam board will fit securely into the section.
Draw a duplicate mark from the bottom to the mid center of the other piece of foam board. Cut away this section with the utility knife.
Connect the images by inserting the top image into the bottom image where the foam core board has been removed. Stand the joined images up onto a table so that each side can be easily seen.
Paint the foam core board sculpture with acrylic paints.
