Rectangular sheet of paper
Most pieces of paper come in a rectangular shape, but if you need to transform a plain rectangular piece of paper into a diamond shape, you can do it with just a few folds and a single cut. Use the diamond-shaped piece of paper to embellish a scrapbook page, or make diamond-shaped pieces of construction paper for your children to use when making craft projects.
