Whether they want to be a princess or a knight in shining armor, many girls and boys love playing games with a toy castle. Instead of buying a castle from the store, work with your children to create one at home. Use recyclable materials you already have, as well as a few craft supplies, to make a one-of-a-kind castle. Not only will you save some money, but you'll also do your part to save the planet.
Select a cardboard box that you're no longer using, such as an empty shoebox or a book box. Tape any flaps and lids of the box closed. Turn it upside-down, so that its bottom side is facing up.
Sketch a door on one side of the overturned box. This castle door can be any shape you desire, such as a square or a half-circle. Use a box cutter to slice along the marked line and create the door opening. This will be the front of the castle.
Find two empty plastic soda bottles. Run a line of white glue along the side of one bottle, and press the bottle on the right side of the front of the castle. Repeat with the other bottle, gluing it to the left side of the front of the box. These will be the castle's front towers.
Cut a cardboard egg crate down each row of egg holders with a pair of scissors. Turn over the containers. Glue these cube-shaped linings along the perimeter of the top of the cardboard box to represent the castle's battlements.
Find an empty cardboard toilet paper roll. Cut four small slits of equal length around its bottom opening. Bend the tabs outward. Place a dab of white glue on the bottom of all four tabs. Put the tube on top of the cardboard box to create a look-out tower.
Roll a piece of discarded paper into a cone shape. Tape it together where the edges meet. Cut along the bottom of the rolled cone with a pair of scissors to create an even bottom of the shape. Place the cone over the top of the soda bottle for a roof of the castle's tower. Repeat the process to make a roof for the other towers.
Paint the entire castle using a paint brush and acrylic paint. Cover all of the recyclable materials with a couple of layers of paint so that you can't see their original colors or logos underneath.
