Douglas Johnston has done some amazing do-it-yourself (DIY) paper planner kit work released under Creative Commons:

Included are 50+ templates of ooey-gooey organisational goodness, some stylish covers, a receipt envelope craft project, a detailed handbook, undated calendars, mix-and-match forms, and more. It’s mostly inspired by Getting, but plenty of generic templates and even a few niggly bits of Covey await the do-it-yourselfers who desire a highly tweakable and uber-configurationable set of dead trees that can help them waste as much time as they save.
