Need Help Fitting a Yardstick in My Wallet

I'm throwing this question out to the Webs -- I have a leftover IKEA paper ruler (it's either a really long yardstick or a really short tape measure, I haven't decided), that I want to fold down to wallet size.

Despite my childhood experience with ninja throwing stars, and my recent forays into dollar bill origami, I really don't know what I'm trying to do, or what the best source of information would be.

Here's my first attempt -- I basically wrapped it around a business card:

It's not very tidy. Someone can do better.

Now, the ruler is a single strip of paper, just over a yard long and 3/4" wide. The only "rules" I'm looking for are:

• You can't rip the strip -- it has to stay a single piece.
  
• It has to be standard wallet sized, so about the size of a normal business card (though it doesn't need to involve a business card.) This means it also has to stay as flat as possible.
  
• It has to be relatively easy to undo.
• Contrariwise, it should hold together pretty well (though if it's kept in a credit card slot, it should be pretty secure).

Why do I need a yardstick in my wallet? I don't really, but if it doesn't take up much room, why not? I mean, it's not like carrying a tape measure around, like certain Farkers:

I've heard of measuring contests at parties, but not like this.

If anyone has any attempts they want to show, suggestions or links to relevant paper-folding resources, please let me know.
