I use bamboo skewers, toothpicks and my sensei recently gave me 10 clear plastic skewers from Japan made for training Neos. You know she is a good sensei, because she doesn't want to be called that.
Over on the slippertalk forum, Jason Fischer mentioned that you only train bean leaf Neos. Also we are supposed to be rotating the plants to encourage growth all around the plant.
coffeecup, can you please elaborate about when you divide plants? How big should they be?
