Looks like a fun concept with a bill.

"A dollar bill has been braided. Close examination reveals that it has two lengthwise slits that extend nearly to the ends of the bill, dividing it into three bands. The braiding is real although the bands have never been separate. It looks impossible.

The bill can be borrowed, transformed into this impossible object, and returned to the owner in less than two minutes. The result is a distinctive memento. It is, as Michael Weber says, "A bill that cannot be spent."

Comes with a companion 20-min DVD demonstrating the step-by-step procedure of how to create the braided bill.

Yes I love this ! But does not work with euros :-( (not good ratio)
But that's ok, just take any magazine paper with good front/back color contrast.

I do too!!!! I must have braided about $113 dollars now!!! After the first 25 it gets easy and you can almost do it blindfolded..... I Leave them everywhere I leave a tip!....LOL!!! This is almost taken the place of my Wonderland Bill..... Almost! And NO one I have tested the theory on has been able to reverse engineer this... even after they undo it.

I think it is the only weakness, easy to unfold.
But that's ok, too bad for them (they surely won't be able to do it after)

With the easier lace leather version, it's already difficult if you don't know the method...
