When I am in Czech Republic, I have a bunch of friends who love drinking herbal tea. But after we drinking the tea, the used tea leaves are going to be waste. To reduce the waste, I went to the kitchen and used blender to make recycled paper with tea leaves and used paper. There is even some nice tea aroma you can feel from the paper. If I put this paper under the light, the material will create the nice pattern with natural herb shade.
