I have what is probably an out-of-the-box question. I am a woodworker but not a boat builder. For years I have thought about building what would actually be a sculptural piece for over the couch in my living room. Think of a large sculpted half hull. I'm thinking it would be 5 to 6 feet in length. For both economy of wood and weight I would like to use thin strips and attached them to ribs/panels. My concern is that the grain direction of the strips to the ribs/panels will be at right angles. If I use non-grain material such as particleboard, plywood, plastic, etc. how will I allow for movement (expansion and contraction across the grain) of the strips. Will they not buckle or warp. I live in Michigan where there are extreme differences in humidity between winter and summer. I plan on using cherry. I hope this explanation is clear. Thanks in advance for any help or suggestions you can offer.
