1. First you have to have a selection of doilies, I think the round ones would work best;
2. Blow up a large balloon and hang it from a piece of string;
3. Paint the doilies with wallpaper glue;
4. Place the doilies on the balloon making sure you overlap them;
5. Leave overnight to dry;
6. Pop the balloon and cut a small opening in the top for light fitting.
