Hi Giulia, here are my instructions for you
1. Take a square piece of paper
2. Take the right point and fold it across so that the point is at the left edge, creating a triangle at the top, flip the whole thing from right to left
3. Take one of the top triangles and fold it down towards you, then fold the other down and away from you
4. Fold it in half diagonally and have the long edge at the bottom
5. Take the right point and fold it across so that the point is at the left edge, creating a triangle at the top
6. Open up the top
7. Have a drink.
Keep each object you create and know that these instruction may not be in the correct order.
Good luck
Ben
