• a pencil
• a piece of heavy paper, a little larger than this page
Cut your paper in half the long way. Tape the end of one half to the end of the other to make a long strip.
Draw a long-necked giraffe, snake, or other long animal stretching from one end of the card to the other. Color it.
Fold the card accordion style.
Now write a birthday message on the folds so that the person who gets your card can read it as he opens each fold.
