How to make a pigeon fly over the Brooklyn Bridge (with a single sheet of paper!)

Step 3 Score

Score along the dotted lines (both dots and dashes) with the ball point pen. Press down firmly but not TOO hard... you don't want to put a hole in your paper. You can use a ruler to make your lines straight.

If you want to write or draw on the inside of the card you should do it now. Flip the paper around so you work on the side which doesn't have the printed lines.
