One session during the Pattern Design course I taught at Victoria College of Art, we explored the concept of Notan. I had been keen to find out if the point in a notan design where the tension between the light and dark areas produced an oscillating balance was the same point for each student. Group critiques of individual's designs proven there was a point when everyone saw it happening.
Another exercise was to find examples of the many different types of patterns we had examined.
Each example was analysed to work out how the pattern was made then it was documented in the student's Pattern Dictionary with a detailed description. By the end of the course, those bulging Pattern Dictionaries had become an invaluable design resource for each student.
