About Wood:
Even though the wood is dry now, you should keep in mind that wood is a natural material that is prone to move with changes in humidity and temperature.
If this occurs, it’s often unnoticeable, but it may cause the wood to warp and shift, or even in worst cases, crack. For this reason, it's important to try and keep the wood pieces in an environment that is relatively stable in temperature and humidity, and to nurture it with some TLC upon occasion.
