Woven endlessly opening card??

[rubberchicken]

Help!!
I had an awesome sample of a card that the paper was woven so that when you opened it, you could endlessly open it because of the way the weaves were attached. Of course, now that I was going to demo it at my class tonight, it has disappeared. Does anyone have instructions on how to do it or at least a picture & some measurements. I would totallly appreciate it.
thanks so much, Michele

I *think* I saw something like this at www.psxdesign.com. Wonder if that's what you're looking for?

EDIT: This probably isn't it, but has anyone made one of these?
