A unique and useful gift idea is to make an egg carton spice/wild flower garden. All you need to do is save your egg carton and all of the egg shells as whole as possible. Then you can paint the carton with what ever fun patterns, shapes, and colors you like. Once the paint has dried you fill the egg shells with dirt and various spice or wild flower seeds. The nutrients that are already in the shell help to nourish the seeds, and provide healthier and quicker garden growth!
