Fourth of July Crafts for Kids: Flour Lawn Stars. Cut out star stencil, sprinkle grass with water (to make the flour stick) and then sprinkle with flour. This idea also works for Canada's July Birthday. Just substitute the star for a Maple Leaf.
"silver star ornament: cut thin strips of newspaper or from a book page. (Or cut a toilet paper roll) Loop each strip until you have enough to form a circle; hot-glue together in the center. Add glittery chipboard stars in the middle for subtle shine.
