This is hammock string video tutorial. This one is sometimes called the Fishnet. The author has gone through it step by step very slowly from the user’s point of view, so you can follow along. It’s easy once you get the hang of it, so don’t give up. Keep trying if you can’t get it. If you have trouble, pause the video and really look carefully at which strings I am using.
