This is where I have been spending quite a bit of time lately. I found SO many tutorials. Like this one for making a Costume Cardboard helmet. (this could be one for Chris)
OH and there is DYI Febreze! I don't use the other stuff but I'm always up for a new homemade product, also this one uses Vodka.
Have fun and make sure you have some time cuz your going to be there for a while.
