Line up the long edges of 2 sheets of construction paper and add a line of tape (on one side only). The tape will be hidden on the inside of the hat, so it doesn't need to be perfect.
Step 2: Fold the paper hat
Fold the paper in half lengthwise, then open it up again. Then fold it width-wise, as shown in the photo.
Rotate the paper as shown in the photo, so that the fold is at the top.
Take each of the top corners and fold them downwards so that the edges line up with the center fold.
Take one layer of the bottom flap and fold it upwards.
Flip the folded paper over. Take the remaining bottom flap and fold it upwards.
Pick up the paper hat and place your thumbs into the opening at the bottom. Pull the two sides apart slightly to make an opening for your head.
Your paper hat can be complete at this point. Or...
Step 3: (Optional) Add string
If the hat isn't staying on your head, you can add string that you can tie under your chin to help keep it in place.Use a single hole punch to make 2 holes on one side of the bottom of the hat. Tie a piece of 12 inch long string through each hole.
