This is a wacky one. A just to see if I can pull it off kind of tessellation . For the most part, I was able to do so successfully. Could be better, but it's a tough one .  It's basically just layers upon layers of elongated hexagonal folds around open back hexagons.  I used thin paper because I figured I would never be able to layer everything using anything thicker.  When I first plotted it out using a small grid of only 16 pleats it seemed so easy and worked beautifully. However, as with many tessellations , adding more repetitions made it exponentially more difficult.  The crease pattern looks pretty innocent, but it's anything but.  As I was folding it, I found myself wondering if maybe medium thickness paper might've been a better choice.  Most of the folds are mountain folds with the exception of the open back hexagons and a set of convergence points. In the diagram the blue dots indicate where the paper should be tucked under. When I drew it I...
