Printable companion libraryThese sheets come from our home science archive. New here? Start with our animated survival series: Zombie Outbreak and Alien Invasion.
Free survival and prepper PDF cheat sheets and printable checklists, drawn by hand in our own comic style. No email, no signup. Print one, tape it up where you build, and work straight down the list when it counts.
Every sheet is the printable companion to a Sketchy Survival 101 video and the deep dive article behind it. Each one gives you the shopping list, the build steps in order, the physics in plain numbers, and the safety rules boxed off so you cannot miss them. They are built to survive a printer and a blackout, so a black and white copy on cheap paper still reads clearly by flashlight. Grab the ones that fit your risk, from grid down heat to cheap home cooling and blackout power, and keep a printed stack in the kit before you need it.
