Useful in gardens, tomato cages are also ripe for repurposing as pretty plant stands. Cut off the spiky feet with a clipper, then spray-paint the cage gold. Set it on its wide end, and fit a pot inside.
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.
