andenvironmen.org has a virtual kit on uses vinegar, olive oil, and backing soda in recipes for cleaning products. It has also container labels to print. You can create laundry detergent, soft scrub, etc - guests just bring their jars.
So, I use this blog to keep track of all the cool things I see and things I don't want to forget but there are two really neat web pages that will do similar things - evernote.com and jott.com - very cool. And these list pads are great.
