How to fold a Paper Cup

Fold a triangle and cross the side corners over each other. Open the top with your fingers and it really holds water.

Steps

Step 1Start with the white side up and turn the paper so a corner points toward you.
Step 2Fold the bottom corner up to the top corner to make a triangle.
Step 3Fold the left corner across to the right edge, so the top edge of the flap is parallel to the bottom edge.
Step 4Fold the right corner across to the left corner of the flap you just made.
Step 5Fold the front layer of the top corner down.
Step 6Fold the remaining layer down behind. The cup is finished. With real paper, spread the top open with your fingers to use it as a cup.
