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.
DIY Idea - string laterns for rustic wedding decor. Wrap PVA-dipped string around a balloon and allow it to dry before popping the balloon - your string ball will be ready to be hung! Different colors, add string lights
