I'm serious about it, but with experimental ideas, so it might be a while before I have anything useful for others.

I want to laser etch business cards on pieces of lasagna, or pieces of hardtack "ship's biscuits"

For today I might try mashing up some grass with some water and baking a solid sheet of it to see what that does. Internet says it does something. Just some practice seeing what can be done with the most basic natural ingredients.

Also want to experiment with banana peels, because supposedly they can make pretty good off white paper without bleaching
