Also, you might also create a bigger one if the one in the video is not big enough.
This project is so pretty and colorful.

Attach the plastic bottles all around the circular metal with metal-plastic ties.
Then, spray paint the bottles to a color of your choice.
Next, hot glue gun the bottles down and put the lids on the bottle.

Repeat in a spiral pattern.
Overall, I love this spiral garden that is made out of plastic bottles.
This is such a great idea if you drink a lot of bottled water.

I think the look of recycling bottles are super cute and creative.
Its a smart way to reuse plastic bottles into something more convenient and useful.
