Back Loop


Product Description


Cut by machine process. Folded and finished by hand.

- - -

I promise that this is made from one single playing card, purely by slitting and folding, without glue or adhesive of any kind. Nothing is cut and then stuck back together. The card can, in theory, be unfolded back to its original shape (although in practice the fragile nature of the card may make this difficult).

I have experimented with many variations on this design over the years, trying to refine all the dimensions involved to produce the tightest possible fit between the loop and the strut that passes through it. This is the best version I can come up with, at the moment, that is still practical to fold. The folding takes quite a while, as you might guess!

Over the years I've found that Back Loop generates quite a range of opinions. It's clearly not the most beautiful or aesthetically pleasing design. However, people who appreciate cerebral and conceptual challenges enjoy the puzzling nature of the design: how can you fold one arm down, and link it around itself, without breaking any of the rules?! I've met a handful of people who understand how to make cards like this, and who make their own versions. However, most people find it pleasantly puzzling and more than a few consider it impossible!
