Step 1, fold a square piece of colored paper edge to edge and a crease appears in the middle.

Step 2, then fold each of these two sides towards the center crease and a new crease appears.

Step 3: Fold each of the two sides into the top and bottom folds to create new creases.

Step 4: Turn the paper over and fold the top and bottom edges toward the center crease to create a new crease. This means that the square of colored paper is evenly divided into eight equal parts.

Step 5: Fold the square in half along the center crease, and then fold each of the two corners of the folded edge toward the first crease on the top, and press the crease in the top two squares.

Step 6, then fold the other opposite side of the square colored paper in half, a crease appears in the middle, and then fold these two sides to the middle crease, a new crease appears.

Step 7, then fold these two sides towards the crease you just made and a new crease appears.

Step 8: Fold the bottom edge toward the center crease and press the crease in the first frame, and do the same with the top edge.

Step 9, then fold the top and bottom sides of the colored paper toward the center crease, then fold the left and right sides toward the front crease.

Step 10: Fold the left and right sides inward along the second crease, and then fold each of the four corners of the center toward the first crease on the outside.

Step 11, then fold each of the two sides of the center outward along the first crease, and then prop up the center confetti along the crease.

Step 12: Fold the top and bottom sides inward along the crease, and fold the sides inward a bit to make it easier for the next step.

Step 13, then gather the left and right sides of the colored paper, and then tuck the four corners of the middle into the layers of colored paper on the top and bottom.
