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.
Blow up a balloon, cover it in doilies using a craft glue. When it's dry, pop the balloon & you have an awesome decoration. Bet you could use it as the lampshade on a small pendant light, too. Great-gramma's and my MIL's doilies may find another use.
