How do I make a bowl out of buttons?

Hi, See Project for Button Bowl using a Balloon.

Hi Carol. I'm Cindy. Begin with a round balloon. Blow it up to the size you want your bowl to be. Then paint the balloon with glue. Up to the height you want your bowl to be. Then paint the back of each button with glue. Put it on the balloon. Continue until you are satisfied with size. It's important that the buttons touch each other. When you have all your buttons in place, paint the bowl with a couple layers of glue. Allow each layer to dry completely before gluing the next layer. After a few layers of glue, pop and gently remove the balloon. You will be left with a "button bowl" to be proud of. Good luck Carol.
