1. First take out a piece of yellow colored paper, fold a diagonal crease, then fold the adjacent two sides symmetrically inward, so that the sideline coincides with the diagonal crease, and then fold the remaining corners toward the center.

2. Then leave a small corner at the top of the triangle, and fold the rest repeatedly into creases.

3. Then take out another piece of square yellow paper, fold the adjacent two sides symmetrically inward, and fold the bottom corner toward the center.

4. Turn the folded triangle upside down, with the vertex facing down, and turn down the upper bottom edge and two corners by a part.

5. Finally, stick the two parts together with double-sided tape and fold them into a simple handmade ice cream.
