I love paper mache. I live near Vancouver, Canada, and like Seattle it rains a lot. I don't leave my mache props outside for more than a few days to be safe, but I havent had any problems with soggy props. Make sure you coat them in something. Spar varnish seals up mache projects well.I have been reading tons of stuff about paper mache used for building props.Once its dry,how durable is it really?I have all the stuff to get started.Just very nervous about making things with it.And what about water proofing it?How is that done?
