These are the supplies we used to make them:
*large wooden craft stick
and this awesome scented paint~found at Walmart.
I also had glitter and glue available and many girls made theirs glittery too.
Before the party I glued the craft stick to the back of the coaster. Then the girls used the stickers to put their name on the stick and freely painted the coaster. The magnet strip was placed on the back of the craft stick. And you're done!
