There are lots of videos on YouTube and other video sharing sites which are useful resources, though it's also worth pointing out that different stringers will have different methods. Please feel free to browse my YouTube Channel (just search for String Doctor) which showcases some of my work and also some reviews and tips... or here's a few to get you started. Contact me via the Get In Touch page if you have any questions relating to the videos. I try to upload videos of some of the more intricate and difficult patterns.
