Its a super easy DIY. I got this off of pinterest.
All you need is...
-hot glue/ super glue
- &&& a bunch of buttons! you can have one color, a few colors, or a bunch of colors
1) blow up the balloon and tie it up at your desired size!
2) From the top of the balloon to the middle of it glue the buttons on. Just make sure you don't use washable and weak elmers glue or something.
3) Then pop the balloon! Let it dry and enjoy!
*If you only have plain colored buttons you can spray paint it afterwards
short tip, Im running out of inspiration!
