I've been commissioned to build and paint a fancy house sign (name, house number) that will be about three-feet wide by two-feet tall. It will be suspended between two posts by eye hooks. I'm undecided as to what kind of wood to use.
The size of the sign rules out a single piece of wood. I'm looking for recommendations on which kind of wood I should use, with rot-resistance a big factor (though the sign will be well primed before decoration and will never be in standing water.) Another concern is joinery and warping. Will biscuits be reliable over the long term, or should I rout tongues and grooves, or join in some other way? TIA!
