I am making a king-size bed for my daughter and her husband. She sent me the attached picture as inspiration for what she would like. I am going to build it from reclaimed wormy chestnut but the advice I am looking for is how you would compensate for wood movement in the headboard where the chevron pattern has the expansion/contraction going in multiple directions. I am normally anal about over-compensating for wood movement just to be safe but thought there might be some unique considerations with this bed. While it is hard to tell from the picture, it does not appear that there are four independently moving panels inside frames - it appears that all four panels are joined. Advice welcome - many thanks.
