Right now, I am currently trying my own method (which may not look how its supposed to, I am not exactl sure HOW it is supposed to look, but I have taken some coconut string as they call it in this article about making palm trees on armorama but what I did was I took the string and broke it into each single thread (which about the same size as normal string) and then dipped it in the paint of my prefrence, and whipped all extra paint with a cloth. I then left it to dry, and will attach them later. The only thing, good or bad, is that the paint didn't really stiffen them up, so if you don't want them to move, or crap, but if you do, it should work alright.
