I attended a workshop run by the Canberra Calligraphy Society last weekend (or maybe the weekend before.) The workshop was based on a SSIW workshop run by Marina Soria. Marina is a very talented Argentinian calligrapher and textile designer.
Marina called her workshop "Empty Space: Womb of Shape". She included a quote from Lao Tzu to underline her meaning of how to treat empty space.
"We mould clay to make pottery, but it is in the empty space where the utility of the jug resides, therefore we should take equal advantage of what it is, just as we recognise the usefulness of what it is not." Lao Tzu, Tao Te Ching, XI.
I made my finished piece into an accordion book structure.
