I would think wax paper - definitely for me because I would use it to start the woodstove or a barrel firing.

Oh, and Tybee, I am definitely going to slide some of this in next year when I am teaching "farm Fridays" but I share lot with the kids in general conversation. I subverted another teacher's "service project" when I subbed a few weeks ago. The kids were supposed to make " don't litter" posters and hang them around school, then pick up trash on the playground. Instead I took them on a scavenger hunt and we recorded all the locations of all the types of recycling available in the building and added this to the posters. I suggested they should pick up trash on the pkayground whenever they see it.
