Step 1: Fold the paper in half along the two diagonal lines to make creases.

Step 2: Fold the four corners toward the center point.

Step 3: Fold the four corners upward, then fold in half along the diagonal midline, and then unfold.

Step 4: Apply a circle of solid glue on the edge, then place the waste paper ball in the center, and then pinch the corners together.

Step 5: Pinch out pleats at the corners, and a cute paper dumpling is ready.
