A pilgrim who travels around the country in search of book-making tools and machines, a collector who collects books handmade by senior craftsmen, a connector who is networked with professionals in the publishing and printing industry, a squirrelly teacher who can’t throw away anything once he gets his hands on it and hides it here and there like an acorn, a cranky old man who finds happiness in the things he collects, but sometimes struggles with insomnia, and the owner of the tools gathered in this book. Since he founded the Book Gongbang Book Art Center in 2001, he has been calling out to the public to put their stories in books made with their own hands. Currently, he has come down to Samrye Culture and Arts Village in Wanju-gun, Jeollabuk-do, and is preparing to create a book art school where students can learn the entire process of making a book in one place. The books he has written include Books that make books well Portfolio that completes designers Bus that makes books Book binding Books that make books well Books that make books well 100 years of Korean letter press printing book and more. He has registered a utility model for ‘Baro strap’, ‘Book workshop jangjeong’, and ‘Nude bookbinding’.
