This may have been covered here, but I couldn't find it if that's the case.

Field & Stream How To

John D. McCann (Are you a member, John?), has a photo guide to building an Altoids kit, and a couple of different sized larger kits. At the end where he lists his resources I thought I would definitely see ETS or Doug Ritter acknowledged, but it wasn't so. I know survival preparedness and mini kits weren't invented by the members here, or Doug, but I can't help but think the author did some research here. I guess things get passed around and nobody knows where the info comes from. I do notice that he his selling a book on the subject, so how many books would he sell if people found this site?
