Embroidery has a long history. The craft in Korea has evolved alongside textiles for over 2,000 years, reflecting cultural identity across historical eras and blurring the boundaries between art and technique.

Sim Yeon-ok, a professor at the Department of Traditional Arts and Crafts at the Korea National University of Cultural Heritage, published her third book “2,000 Years of Korean Embroidery” last month to shed light on the lesser-known mastery of Korean embroidery.

While previous research on Korean embroidery focused on aesthetics, Sim, as a textile engineer, looked at embroidered works through a microscope to examine their details and structure. Sim said her former professor Min Gil-ja, a pioneer in Korean textile research, inspired her to delve into the field.

“Fiber and textiles should be understood and researched from an engineering perspective, as structural design is inseparable from the creation of fabric. Most of Korea’s clothing history was studied by historians and domestic science majors, who did not have much knowledge of engineering,” Sim said. “Professor Min encouraged me to study in China as understanding Chinese textiles was essential for studying Korean textiles considering the exchange between the East Asian countries.”

Sim went to the China Textile University in Shanghai, now Donghua University, in 1992, right after diplomatic ties between China and Korea were established. “I am one of the first South Korean doctoral students in China,” Sim said.

He wrote in English: “2,000 Years of Korean Embroidery”-My mom’s masterpiece on Korean embroidery, worthy of huge respect.

If you want to see a bit of the book go HERE.  Thank you to IG ytjiw0909 for the information on where to search for it!  I wish her great success with it.  It would be nice if they featured her in Koreana Magazine again!  I love that magazine!

Here are a few screen shots of the book:

I also discovered that she was in here in the US in February of this year!  She took part in a Symposium about Korean Buddhist Images and Dedication Practice in Washington DC!  You can read about the program HERE.  WOOw!

This is her resume… she is an expert in her field!



Yes, this means that she speaks Chinese too!  (She speaks English very well too.)
