If you have been following me for any length of time, you know that I am all about recycling and cheap! I don't know if I can get any cheaper than this and my kids love this play set. We washed out some juice and milk cartons, cut them in half and painted them with craft paint. Then, we cut doors into our little "houses" and added some little details. Next, we went out into the yard in search of some smallish rocks. We looked for ones that we were able to stand up. Then we painted those, added googly eyes and drew on mouths. Voila! Done and done. Cute little play houses for our little pet rocks. So fun, so cheap and recycling at the same time. What's not to love??
