This is an idea I had back in September 2019. I folded it then, but upon revisiting decided it warranted a new attempt.  The first time I used ordinary paper. It came out okay.  This time around I opted for kraft paper. This stuff is like folding thin cardboard.  It does not backlight well. But I still like the finished product.  Still working on neatening up the reverse side.  Update: adding a crease pattern photo. It's probably not necessary for most folders, but if you want it, it's here. 

 I was going through old models and set aside a few that I felt were interesting, but that I had not executed properly the first time around.  This is one of those.  It's small hexagon twists and triangle twists that are between one pleat and two. The hexagons and the triangles live on  opposite sides of the paper. There is a need (if flatness is to be achieved) to twist the edges adjacent to the triangle points a little further. This is how the resultant arms off of the hexes are achieved.  It's a very tight fit. It folds easiest when the hex side is worked more.  The end result is pretty interesting. 

This is another tessellation by Arseniy K that I fussed over until I had it figured out at last. Once I'd discovered the crease pattern, I realized it was going to be pretty tricky. It's small and compact. Still, I pressed onward, in spite of my doubt.  It took a while to fold. The paper I was using was not thrilled about what I was trying to do to it.  Eventually, it acquiesced to my stubbornness and I had success. I found it very helpful to work mostly on  the reverse side. I was never confident I would actually complete the fold, but I had nothing else to do other than try. I continued on despite my ambivalence and it did come to fruition.  That's the thing about tricky folds... they simultaneously inspire and intimidate me.  It's an interesting experience to see the paper go from a floppy mess of grid and pre-creases to over time finally surrendering to these mad configurations.   It's almost an addiction. Or maybe it literally is.  I do have ...

  Not sure how I came up with this one. It's an odd idea I had. It's pretty basic. Square grid tessellations always feel easier to me. They probably literally are easier. Four edges vs. the six edges of a hexagonal design is a little less complex.  The triangle grid, hex design is definitely my preference. I thrive on the difficulty.  Still, I like to occasionally go back to the square grid. It just feels like something I should remain acquainted with working. Have to keep those skills sharp.  My first ever major tessellation success was the high density clover tess. It cemented my love of the genre and set me off on the path to exploring all the other  possible complexities.  No matter how you prefer to fold or how long you've been doing it, there's always more to enjoy and learn. 

As I was figuring a design by someone else, I accidentally landed on this idea.  It's kind of  cool in a simple sort of way.  I wanted to squash fold the flaps, but it's not an easy task with a small model. They don't always behave as we would want.  I actually did do the squash folds on the center, but that's as far as I got. No picture of that yet.  At any rate, it's an interesting little idea. Not the most complex or challenging, but worth a go nonetheless.
