| Two Extremes of the Octa-ConVase Variations |
Designing the alternate Octa-ConVases is basically a study of the effects of changing the area of the octa-base and the mouth, and how they affect the gradient of the wall. At times, one may focus on the gradient instead-such as to fold a model with up-right vertical walls.
It is the same piece of square paper, when something gains, others have to give. The most noticeable resulting varience is usually the height of the model; and it also makes the models look tall and thin or short and fat. The picture above demostrates two extremes of the Octa-ConVase variations.
How to Change the Base Area?
The control is in Step 2.
The picture shows the two extremes I would recomend. The resulting models look similar to the two in the picture above.
You can of course use anthing in between. Beyond the extreme limits, the model will be technically wanting.
How to widen the mouth?
The control is in Step 9.
I trust the picture is self-explanatory. The one on the right is the standard model. I don't recommend widening beyong the Vertical Central Line (VCL), as this makes the top edge too narrow.

And here is the top view:
That's it. Want more challenges? Try folding this one with all folds hiden inside the model making them invisible, giving you a clean and zen look:
