I recently took a class on calligraphy, which was quite well done. The issue I have though, is that I spent around $20 just to have the information organized. A simple Google or YouTube search and you can find much of the same information. The nice thing about Skillshare is it breaks it up into lessons, but if you're not 100% sure you're going to finish the class and you just want a taste, there are many FREE resources available all around the web. I'd go there first.
