Hi, I along with my family all love the movie Christmas Vacation. I bought the moose mugs and now Im going to try and build the advent house. Adventhouseplans.com gives some good info and some of the materials but Im wondering if anyone here has any knowledge of some kind of craft bricks to use on the facade of the house. Also does anyone know what would be a good material to make windows out of? I heard vellum. Thanks.
