Flowers and Gems Origami Tessellation
This one is small offset hex twists with teardrop shapes off of them and blunt pyramids on the back.
The pyramids on the back overlap some, but not enough to make it easy to nestle them together.
So when I went to flatten it, I just did the best I could to get everything to play nicely together. It didn't work out perfectly, but the front has a nice finish in my opinion.
I like how the backside pyramids result in funky shapes on the front.
The benefit of using small hex twists that are folded similarly to open back hex twists is that you can create tessellations that fit nicely on a smaller grid that are not possible using a classic small hex twist.
