My boys wanted to build bird houses, so I got online and found some kits that had the pieces cut and included the nails, paint, and glue. We only did 4 (we left Christian and Lily out.) The children sanded and painted them themselves. Chelsea and Nick were able to assemble them themselves which was a difficult task because the nails were very small. I uses a hot glue gun on Alex's and Anthony's. They were thrilled with the finished product and we hung them outside in a tree.
