1. Various white dinnerware from Goodwill: $2.00
2. Sharpie: You probably already have one
This is such an easy (and cheap) DIY project. Just draw whatever patterns you like on some cheap, plain dinnerware with a Sharpie!
*Update: I've had a lot of people ask if the designs stay on when you wash it. I made the mistake of putting one of them in the dishwasher and it did wear off. :( But, if you gently hand wash them, they should be fine! Also, a helpful reader informed me that you can buy porcelain pens that write like a sharpie, and then you bake the dishes and it seals in the ink - definitely something to consider for this project if you want the dishes to be more durable!
