<human>: Here is a goal: How do you store birch bark after it has been removed from a birch tree?

Which way makes more sense to accomplish this goal?

OPTIONS:
- Lay the bark on a flat surface. Grasp the top end and gently roll it downwards so that it is rolled longways (down the trunk).
- Lay the bark on a flat surface. Grasp the top end and gently roll it downwards so that it is rolled longways (up the trunk).
