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.
Glue buttons around a balloon. When they dry pop the balloon and you'll have a button bowl. A creative idea to use it to hold some light objects such as candies, chocolates, accessories, tissues and so on.
