I'm still working on the roof - slow progress! It's best to wait until each tile has set as I don't want the tiles to stick only to each other and not the roof.
I've also cut the ends of some cocktail sticks and pasted them to the roofs of the dormer windows to give the first tiles a lift.
I've printed some nice little 1/12 book designs and have cut/glued them tonight. They need an overnight press to make them flat.
