To start blow up the balloon. Set up balloon and grab a roll of painter's tape and use it as a stand for balloon.
Once balloon is set up, apply a layer of glue and spread the glue around using the paint brush and then let it sit for about two hours to fully dry.
Apply Mod Podge & add buttons. Choose a slightly large button to put in the middle. Make sure every button touched another. Try to keep the buttons evenly distributed around the big button in the middle and continued adding buttons until they were all applied to the balloon.
After all buttons are adhered to the balloon, apply 2 more coats of Mod Podge letting each coat dry fully before applying another.
Pop balloon once the Mod Podge is dry. After popping the balloon carefully pulled it out of the dish. This is really an easy project!
