Anonymous Double Pointeds

[macabre-grrl.livejournal.com]

Does anyone have a good way of telling the sizes of their double pointeds if the needles get loose from their package/all mixed up/etc?

A long time ago I saw a website where a knitter figured out how to use a wire gauge card to do this, but she had to do a lot of converting.
