Saw the pin earlier about cutting glass, but I'm sold using old bottles. If I can only find the pin again. make glass sets from old bottles, using a glass cutting technique with yarn, nail polish remover and a flame!
Since I kill plants on a regular basis, this would be a wonderful addition to my indoor gardening! I've seen plastic versions, but I'd rather not grow edibles in BPA. Self-watering planter made from recycled wine bottles.
