How will it bend ?
Professions like joiners and carpenter always know how wooden boards behave. How they will bend, in wich direction and so on. That´s because of joiners are really into the knowledge of wood.
I asked myself how to visualize the behavior of wood to make it easy to understand. So what i come up with is an slice of a fresh cut tree thats really wet. I´m going to cut it like they would do it in a Sawmill. Because it´s a wet peace of wood it will bend while it´s drying. That will show the behavior of wooden boards in a exaggerated way.
