A few more steps and this becomes a Kayak. Inside the Canoe you can pull where to two ends meet and round them off so it's hollow inside. The diagram is actually a Kayak. I just stopped a few steps before completion.

Difficulty : Beginner
Number of Bills : 1

Any bill will do but the 1$ is nice as you can see O-N-E on the bottom.
