A big case of boredom sometimes requires a big cure--like this towering, build-it-yourself skyscraper. Made from stuff you already have around the house, it can keep children busy for hours. Start by collecting cardboard boxes in various sizes.
Tape the boxes shut with packing tape, then stack and tape them atop each other. Using markers or crayons, your kids can decorate the boxes with windows, columns, gargoyles, mailboxes and so on. They might also add some 3-D touches, such as tissue paper flowers and bushes, construction paper flags or even some plastic figurines.
CRAFTER'S TIP: If you don't have plain brown boxes, wrap yours with butcher paper or turn them inside out and tape them back together.
