This contest is about structures. Not buildings, but closeup shots of the material that is used to build something! Your photo should show a repeating pattern of the structure of a certain material. Without a clear pattern, your entry won't be on-theme.
It could be something with walls and floors, or the knitting structure of a sweater. It could be made from metal, paper, grass or whatever, but it must have been made by humans. Give us your most artistic shot emphasizing structure only, no other objects (including animals and humans) are allowed in your image. Let members guess what your picture shows.
