Sweet looking pup @CurryLeafTreehugger sorry you lost her. Beagle? I always had a pet beagle growing up as a kid, hilariously smart and sweet dogs! @ataxian Haven't seen you around (the UD world) in a while.. welcome! For the UD wood is: physical structure, insulation and aesthetics. I have made some 'cases' in non-wood materials but it's hard to find ones that are: safe, affordable, have good workability and also have proper insulation properties. Many woods have all those properties plus beauty which make it a good choice. Did you have something specific in mind for a different material? Wood is also special to/for me because I grew up in a tiny remote logging town in the middle of the woods. All my family is/was loggers and/or woodworkers so I just naturally gravitate to wood.
