Have you heard of the site, Built By Kids? It’s filled with projects that are (you guessed it) built by kids, with kids and for kids. Since winter is inching closer and more of the day will be spent inside, it’s the perfect time to gather up ideas for those “I’m bored” moments. I’m especially loving this chic, cardboard castle made pretty with neon duct tape. Check out a few more kid-friendly projects below.
