Step 5: Finally, fold the two ends in half towards the middle, and then open the paper to tidy it up.

The second folding method (gift box):

Step 1: Divide the rectangular paper into three equal parts.

Step 2: Fold the corner of the upper left corner to the first crease, and then fold the rest to this corner and expand to get the crease; The other end is folded in the same way.

Step 3: Fold the diagonal of the small squares at both ends of the mark into creases.

Step 4: separate the first category on the right, then fold the diagonal line in the middle inward and then back along the other diagonal line; The folding method on the left is the same as that on the right, and a three-dimensional rectangle is obtained.
