I have been reading up how to do "Papier Appliqué"(thanks to you and Lucius). It seems that the glues used were biodegradable as they were made from flour and starch etc. The use of modern glues such as Titebond has revolutionised such methods and is mold and damp resistant.
So this is definetely an option since its relatively light weight and easy to make.
