I decided to do 6 coasters. I stopped at Home Depot and picked up plain white tiles in the flooring department - they are 16 cents a piece so it was about a buck total (cheapest Home Depot trip EVER!).
Then I stopped at Hobby Lobby and picked up two sheets of scrapbook paper. One that would actually match our living room and one that I just love because I'm obsessed with birds.
When I finished, some of them looked a little wrinkly
But they straightened out as they dried.
The next day, I sprayed them with clear spraypaint a few times just to ensure they were drink resistent. Once they dry, just stick felt pads to the bottom of each so they don't scratch your furniture (you can buy a whole package at Hobby Lobby for 99 cents).
Quick, cheap, and easy project for something that we needed in our living room!
