Taking Inventory?

[Scythe13]

I was thinking more along the lines of a sheet of paper that helps you keep track of what you might have. This would then provide you with knowledge of what more things you'd need to get hold of. I wasn't thinking of a computer based system. If you could imagine, a sheet of paper on a clipboard, that you will keep stored in your loft, so you will always be able to keep a track of what you have available. Maybe one hidden in your kitchen somewhere so you can track the hidden tins you may have around the rest of the house.

Just as a way to know what you have, what you need more of, and the alike.
