I can't take credit for this idea, it was given to me years ago by +Jackie G . Easy to do and very helpful for those hard to read or non-existent census headings.
Copies of blank census forms can be found at http://www.ancestry.com/download/forms
Print them out, cut off the headings at the top. They are not all the same size, and some are landscape and some are portrait, but make as close to the same size as possible.
Laminate for sturdiness, and attach to a keyring or index card ring.
That's all there is to it.
