Sorry, I forgot quite an important point. If you do use wood, then it
should be very hard wood, and extremely well sealed. ( soaked in warm
epoxy and then finished when dry), as otherwise it may swell when it
gets wet, and either be impossible to remove, or even damage the
blank.

I believe the technical name is "stabilized wood"
There are plenty of websites who specialize in such, or you can do as
Mike says above.
