DIY PROJECT:COFFEE CAN LANTERNS - Instead of setting them up with clamps and wood and stuff I have seen the same thing done where you just fill the can with water and freeze. Which means you then have a good sturdy surface to hammer the designs into.
Artwork made from spray painted v silhouette leaves. paint canvas the color you want the leaves. put leaves on canvas and spray paint the background color you want. remove leaves and you will see the color come through.
