I don't know if I have a proper answer for you. For so many years folding was only following the instructions sometimes with success and sometimes without. It was fun, but it wasn't a passion. The only model I experimented with was the origami brocade and I didn't change the unit only the construction. You can make a weirdly flat pincushion like model if you add enough units and you can fuse two spheres together. Then something changed and every night for about a month I started with the fortune teller and tried to make something new more often than not succeeding. I now know how to make two Christmas decorations, connecting boats, spinning tops, windmills, a collapsible cube, triangular gift box with and without handles, a snap into shape sphere a few weird looking solids and a five and eight sided fortune teller it was eye-opening and I haven't looked back.
