Christmas Tree v1

There are many origami Christmas tree models, so I focused on a few goals when designing my version. 1) One uncut square. 2) Color-changed star and trunk. 3) Well-defined star shape. 4) Each tier is broader and taller than the tier above it.

I managed to achieve those goals with this model. It is also possible to add extra tiers with the same increase in proportions to the tree. Unfortunately, this model's precise proportions are tedious to fold. I recommend Christmas Tree v2 for a quicker folding experience.

This model can be made to stand by itself by opening up the model and folding the tree trunk inside.
