Keep cool on your outdoor summer adventures! This project was created with the limited edition Summer Fun bundle. We’ve designed this bundle to keep you busy with fun, easy projects while The Heat is On! Each project uses easy-to-find household objects, so you won’t have to exert yourself while it’s Hot! Hot! Hot!
