Whether there's snow or sand piled outside the door, your family can celebrate the spirit of the season with these winter-inspired indoor projects. Transform laundry soap into snowmen that can stand up to any heat, use sugar cubes to build mini igloos that would make an Eskimo proud, and turn poster board and foam rubber into a winter wonderland. All are easy to make and utilize common household supplies you probably already have in your cupboard. Plus, they're the perfect boredom busters for sick days, snow days, and holidays.
