I will try to put this into words so forgive me in advance if I don't explain it well. Start with plant standing straight up. Bend the top down and tie it to the rim of the container. You now have a plant that looks like an upside down U. Tie the top center of this "U" to the rim of the pot as well. As the plant grows keep it tied to the rim of the pot so that it grows in a circle. If that doesn't make sense, sorry, its the best my stoned ass can do. Also don't bend stems too much, too fast. It will take a few days to slowly shape the plant. This method always does me right. I just hope it makes enough sense to help you. Good Luck
