I was first introduced to this video by a skilshare class that I took on calligraphy. The video taught me a lot about the history of black letter. Also that reading black letter is a lot easier than normal text. I really have been enjoying learning the history of callligraphy.
The reason is because I have been teaching myself calligraphy for so long it seems that the more I learn the more I enjoy it. The same can be said for me when it comes to graphic design.
