Choose one design principle.
Search for three images – one from contemporary metalwork, one from contemporary fiber, and one from contemporary woodworking – that each illustrates the same design principle. 
Post the images in the discussion (cite your source!) Write 1-2 sentences per image. For each work discuss how the chosen design principle is exhibited by the work you chose, why you chose this image, and how it is an example of the contemporary craft discipline you propose.
