Go to the beach and collect all the wonderful things you can find. I used all empty crab shells and a couple of crab legs. I love their rich colors.
Take a photo frame and remove the glass. If the cardboard backing on the frame isn't black or white, use some acrylic paint to cover it. Arrange your found object in your frame. Try to create a balance with your design to make it pleasing the eye. I built a pyramid with mine.
