Purchase a book that teaches Korean calligraphy, such as In-shik Shon's "Teaching Calligraphy (I, II)," available from Poori Publishing Company. This book teaches calligraphy with the idea that it is a means of transmitting Korean culture and heritage. Another option is Mi-kyong Lee's "Korean Calligraphy," available from the Hagwonsa publishing company. It is written in Korean, but it provides instructions for learning calligraphy. A calligraphy book will supplement other teaching methods so you can study in your spare time outside of a formal classroom setting.
Locate a Korean cultural center or society in your area. Korean calligraphy classes are often offered to communities. For example, the Donghwa Cultural Foundation in Englewood, New Jersey, hosts a Korean calligraphy club for youth in the community that meets each week. Check social websites such as MeetUp.com for local Korean language groups in your area that may offer calligraphy classes. Korean calligraphy is also often offered as part of East Asian Studies in colleges and universities.
Attend calligraphy classes regularly. Learning Korean calligraphy will take a significant amount of time and effort. As you learn more and more about the Korean culture, your knowledge and appreciation of the place of calligraphy in its history will increase.
