Don't forget that kit begins with what's already on hand (or in general possession). For example the old pocket knife corroding away in a drawer or closet could easily be your EDC, at least at first.

Most of us who are building preparedness from ... well, from not much ... should probably have some matches around, if not a lighter or two.

Add those, a large bottle of water, and that throw blanket that's in the closet, and you've got yourself a very basic kit to pack in the trunk of the car around the spare tire.

Granted, this is by no means a permanent idea; it's meant to be built upon, improved, and probably completely replaced in time.
