Hong Kong-based artist Alfred Chen takes a single thread of yarn over 5,000 meters long and weaves it around a frame made up of around 300 metal nails to create stunningly realistic celebrity portraits.
Chen starts the creative process by selecting a digital image he wants to recreate. He then changes the color version to grayscale, adjusting the brightness and contrast to better expose the shadows and highlights he will have to recreate with thread. Finally, he relies on an algorithm that tells him exactly how to weave a single thread around the 300 metal nails in order to recreate the picture in real life. Then the real work begins.
