One of Avery's new favorite crafts to do is these easy and fun tie dye rocks. Her favorite part of it is going on a "rock hunt" to find the biggest and best rocks to color. Then you just heat them on a cookie sheet in the oven. Pull them out one at a time, put them on foil, and color them with crayons. The wax melts and when to mix it together it swirls to make them look like this. Pretty cool (and cheap!).
After she got done coloring the rocks, we put them out in the garden. A very cool addition!
