Amazing amount of effort has gone into the building of this castle Tom. {bravo}}If it was mine I would like to ensure it kept it's shape by trying to coat in some strengthen agent. Maybe not needed, but for me I liken it to some jigzaws I have done, after the effort rather than see them broken up, would like them glued in tact and framed forever. With this skill any building could be done, how clever, cheers, Robin.
