Putting them together:
You find the number one on one pattern, you connect it to the other number one on the other pattern. Then, you do number two. You connect that one to number two as well. But number three, watch out for that one! It also connects to number three.
This isn't rocket surgery. :bendover: :gun5:
Fold the "peak lines" out and the "valley lines" in.
Oh, and to connect the numbers, you can use tape, glue, or soda pop. Your choice.
