If you're a poor college student, like me, you probably have tons of restaurant coasters lying around. I don't have any regular coasters.
Grab some magazines and cut out patterns pictures and designs you like! Girly magazines are great cause they have lots of colorful ads. Catalogs would be good too!
Arrange the images on to the coaster. If it's a big images you can fold the rest over onto the other side and cover both sides! I Mod Podge the images on. You can use glue if you don't have Mod Podge.
After both sides are done I picked the side I liked best for the top and covered that in glitter paint.
Then I recommend coating the coaster in clear spray paint or varnish to protect it.
And without spending hardly anything you have some cute coasters!
