The best type of cardboard for making recycled craft projects is chipboard. This type of cardboard is commonly found in product packaging such as cereal boxes, soda boxes and gift boxes. Chipboard is better for recycled crafts because it's flat, smooth and thin and lacks the fluting of corrugated cardboard. To create recycled cardboard crafts, you will need a pair of scissors, some craft glue or a glue stick, a craft blade and some craft paint and brushes. Recycled cardboard is useful for making crafts such as Christmas ornaments, toys, working airplanes, picture frames, hats, models of buildings and more. Cardboard toilet paper and paper towel rolls are also useful for making armatures for crafts such as human and animal figures. Corrugated cardboard makes an excellent building material. You can use it to make crafts such as cars, trucks, trains, airplanes, castles and puppet theaters. You can find many ideas for recycled cardboard craft projects on websites such as FamilyFun.com and Kaboose.com. Reusing cardboard in crafts is easy to do, so you can come up with many of your own projects.
