Either way. Whatever and however you can make it work but it works pretty well and is cheap as hell. I think a box of paper clips is like $3. As you can see in the picture I was too lazy to actually make the proper bends. I just used the bends the clip had. LOL! You can even hook a higher branch to a lower branch that you're LSTing and bend it down too!oh, so you use it like a chain? i thought you used it like that tool i posted.
I was even thinking of a light wire that you could wrap around the branch and bend it however you wanted like a pipe cleaner but I'm not sure how the pressure on the branch would affect the plant. Look at how they tie Bonsai Trees and it'll give you a ton of LST ideas. Japanese are experts in LST.
