If you shop online at all, you probably have quite a stash of cardboard boxes. Besides sending gifts to loved ones far away, they can be used to make some frugal and cool things.
Try your hand at a shadow box. You can put in an old fashioned scene, a "Nativity Scene," a mountain covered with snow or let your imagination roam. Use pictures from old Christmas cards, advertisements, catalogs or whatever strikes you as interesting.
You can use small boxes in lieu of Christmas stockings or baskets, filling them for specific individuals, or making more generic, frugal last minute gifts out of them. Cover them inside and out with wrapping paper or foil.
Fill a few with candy, cookies, notepads, etc., wrap and have them ready for those "Oh, no, I need another gift!" times. If you don't use them all, give them away to the postman, a retirement home or charity.
