I've started making a lot of my own. I keep an inventory of all my gear and have collected so much survival/preparedness information that its difficult to locate the correct information. So I've started organizing it into quick reference cards and checklists. I have two printers capable of printing 4x6 photos so I bought a bunch of 4x6 index cards and made a 4x6 template in OpenOffice (I have to use Excel at work and between the bugs, oversized files and non compatibility throughout different versions I no longer trust it at home, plus I can take portable openoffice on a flash drive with my files). I made a simple checklist for truck maintenance showing which direction to rotate the tires, lug nut torque and the grease fittings, reference cards for my radios and electronic gear and checklists for loading camping gear and preps when/if we have to go.
