Here is how to make your paper square. If your paper is already square, congratulations! You can skip this step. :)
Fold one corner of the paper down to form a triangle with a small piece at the end.
Draw a line along the bottom. Unfold.
Cut along the line.
You now have a perfect square!
Fold in half diagonally.
Fold the two bottom corners to the center.
Fold the top layer, on the top, down as far as it can go.
Repeat for the other side.
Your cup should look like this.
Gently open the top...
And Voila! You have yourself a creative cup that you can fill with almost anything. If you wanted to, you could get a large piece of paper and make it able to hold something larger! 😊
