Whoa. For some reason I never thought that hemp twine came in other colors. This was submitted by a reader:
Just a head's up. You can get colored hemp twine from dick blick art supplies. I usually just use a little framesaver (technically linseed oil) to keep it in place make it semi waterproof. The longest i've had it on the bike like that was a year and a half (i like to change things up on a regular basis), but it help up just fine and took some effort to remove after that time.
