I was pleasantly surprised that this was a 1-on-1 class. It takes place in the artist's cute studio in Hongdae, very close to the train station. She was such a delight. The outline is done for you before you come, then she demonstrates how to fill it in. She's bubbly, friendly, and conversational. Even though we had a language barrier, we still managed happily communicating just fine. I decided a couple of days beforehand to do this and am so happy I did. This was a unique and enjoyable experience.
