This is a set of items for dressmaking and fashion design, including three textbooks, one supplement, one correction problem book, pattern paper, a DVD, and fabric for corrections. I signed up for the course to gain related knowledge for my work, but unfortunately, I couldn't find the time and had to give up. I am unable to provide correction services, but I hope this set can be useful for those who are challenging themselves to obtain a qualification. I only briefly looked through the beginning of textbook 1, and the rest have only been checked for missing pages or items, and are completely unused. Please check the images and purchase with your understanding. Thank you.
