I found this when I was googling images for indoor plant ideas and I thought they looked cute.
The person that makes them in the U.S. sells them on Etsy, but for obvious reasons they do not ship well.
Tiny little terrariums in a light bulb. What an interesting idea!!!
Juliette at tinyterra has some interesting ideas. Have a look at her website.
There was also a website – The Hipster Home – that shows you how to make them.
And it doesnt look that hard either.
