Cut a rectangle of cardboard—about 3 inches by 4 inches. Now, cut a slit down the middle of the short side, stopping an inch from the edge. This creates a little U-shape. I call it a “pom pom loom,” but it’s really just recycled snack packaging.
Why do this? The cardboard gives you a consistent size and saves your fingers from yarn burn. Plus, it’s a great excuse to raid the recycling bin. See, Mom? I told you I’d use that cereal box.
