I see this as an educational tool. This online library of fashion design videos serve as a course in sewing. Assembled by FIT (Fashion Institute of Technology) instructor Francesca Sterlacci, a viewer will gain an education, though not a degree, through careful watching and practice. The goal is to make accessible the expertise of design professionals without having to pay thousands in tuition or live in NYC. (I thought it was free, but there is a charge.) She also notes that fewer people in the industry master these skills since so many jobs go overseas.
Take a look at the over 100 EPL holdings on fashion. We have many other materials on knitting, crocheting, and assorted handicrafts.
