  1. Oh yes, who doesn’t love fun rainbow crafts. Our little one just turned 3 and she loves painting rocks with rainbow designs, so I might grab a few of these to try out with her.

  2. Great ideas! My wee girl is somewhere between baby and toddler. Her passions are destroying and eating everything she comes into contact with. Looking forward to the day we can do a few more of these projects 🙂
