You're going to love it!! First of all, if you'd like- you can make your own

Here are some cool technique tutorials http://www.hometalk.com/diy/paint/chalk-paint-carved-surfaces-techniques-4219519 http://www.hometalk.com/diy/-7320393

The most important thing is to make sure you start with a clean surface! (Even though you don't need to sand with chalk paint, no paint will stick to an unclean surface.)

I clean my furniture with 50/50 water and white vinegar, and a few drops of blue Dawn detergent for extra grimy pieces. After cleaning, rinse very well and allow to dry.

Also- chalk paint dries very fast, so you need to move quickly. Once you are done painting, you'll need to seal the finish with a topcoat, which will differ depending on the brand you choose.

Good luck!
