Cut by machine process. Folded and finished by hand.

One of the most ambitious designs I've ever come up with.
It's basically an exercise in combining positive and negative space as compactly as possible. I hatched this design back in the day when I had to cut each card by hand. This design represented the limit of intricacy that I could achieve at that time.
Criss Cross isn't the prettiest design to look at, but it's a great one to actually hold and to study. People love turning this one over and over in their hands and seeing how it all locks together. It can keep some people quietly occupied for hours.
