We present new developments building off the work of Lang et al. in hex pleating as a method for designing representational origami models, including both uniaxial and non-uniaxial techniques. Compared to box pleating, hex pleating offers greater flexibility of layer distribution, better ability to incorporate structural textures, and a more organic appearance. We will describe how to pack basic uniaxial trees with hex pleating, how packings can be modified to redistribute paper thickness throughout the model, how to incorporate level shifters, and finally discuss hex pleating as a means of creating representational polyhedra.
