I hear ya on the biscuit cuts. That's an interesting idea. I'm going to think about that and how to perhaps do something similiar so I don't have to cut into the vinyl porch posts. Another problem is, because of the gingerbread's design, I can't counter-sink any screws into the gingerbread (which would screw THROUGH the vinyl and into the 4x4 PT wood underneath the vinyl.) I need to be mindful of some movement, I suppose, with the temp fluxuations. Maybe not. Gluing both sides of the gingerbread will CERTAINLY make that 'problem' a foregone conclusion.
