Please have a look at this blog with it's beautiful photos: Vana-Olevi. It's all in Estonian, but the photos tell a lot. And Mr Google can translate for you :) Stumbling, that's true, but even a stumbling text can be understandable. Also watch the videos, they are amazing. To make it even more amazing: the shepherd's name is Ylle, which means "woolen fabric" or "made of wool" in Swedish.
