this looks like a great mothers day/grandparent gift/ teacher gift idea. Lots of options with flowerpots, buckets, etc to put it in and with the types of flowers or stems to use and filling in the pail.
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.
