The advantages to taking a Craftsy course is that it's available to watch whenever you want, as many times as you want. You can ask questions and receive feedback from the instructor and other students. You can post photos of your projects and be inspired by seeing other people's projects.
In my regular live, in-person tatting classes such as held at craft fairs, I can only teach maybe 5 beginners at a time. But, in my online Craftsy course, there is the potential to teach thousands of students - yet, each student can see close-up views in HD quality video and audio to see exactly how the tatting is being done.
