This was the perfect activity for a quiet afternoon in Seoul. The shop is slightly hard to find, but the staff is super helpful. I was even running late (over 15 minutes late, I felt so bad lol), but the instructor was super understanding and patient. They speak perfect English and know their stuff. I was able to ask questions as much as I wanted, which was honestly probably too much.
Overall I highly recommend this course to anyone staying in Seoul for a while. You get to learn something pretty practical and leave the shop with a beautiful flower arrangement, where's the downside to that?
