Kokedama is a Japanese planting technique that creates moss balls. You can hang the moss balls, put them on a plate or a bowl. I saw on design*Sponge a reference to a kokedama tutorial by the creative Dutch girl called Aura Scaringi.
I was intrigued by the technique so I dug the Web further to get more information. I found two videos produced by a Japanese blogger who demonstrated different ways to make your own kokedama. Here is the first one.
