not to bad ... but tell me .. now I dont hope its one of them dental floss with tast (mentol)
also .. I usealy use something that can "give in" a bit .. and is soft so I dont hurt the stems ..
most importent tho ..
is to start by makeing one or two strings around the bottom of the main steam and secure it/them in the other direction then you plant to LST ..
so you dont unpot/root your plant by accident when you pull it down ..
but ther is a lot of guides out ther .. with a lot of need tricks .. like doing it when you just gave em water to steams are soft so they dont snap ..
also .. when repotting .. clip the strings .. and if you plant on start LST agin (wait a day or two untill plants is`t stressd from the repotting) then plant it a littel off center .. so you have more room to work with (not completly out at the side .. but a few inchs off so you have more room to bend it down agin ..
I could keep on .. ask if you have any questions and do some research
