This is what the finished vase from the plastic bottle looks like. If you do not look like it looks like it is made of thin glass or crystal.
1. Cut the top of the bottle.
2. Measure the future of the neck of the vase and cut it into thin stripes
3. Generate all strips to the outer side of the bottle
4. Turn over the bottle and put it on a flat surface, then push it to it, for all that would provide smooth edges of the neck of the future vase.
5. Bend strip for two standing strips
6. For the next strip, do the same. And so as long as the non-bent strips remain.
7. Vase from plastic bottles is ready.
