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:
- 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).
