Well, I really love those terrariums Lin, beautiful! How do you get the walls clean in the water jug after you get it planted? Actually, I should first ask how in heck you got it planted? I don't think I have chopsticks long enough for that. I have an old wavy glass water jug that I would love to do something like that in but I can't figure out how to get the plants and the soil and ??? do you use charcoal?
