I guess my favourite comment on the difference between craft & art describes a craft as specific technique. Practice your technique and apply your skill to create a piece of art. (or along those lines). So I have spent the last 3 months or so crocheting rag rugs. Huge amounts of time have been spent re-crocheting when the colours have been wrong, and even more time re-crocheting when the edges have not laid flat. This is not a craft for those with arthritic hands and wrists - it is very physical. I'll upload photos from tomorrow.
Meanwhile here is a section of the amazing midden on cockatoo island - teacups for the white settlers, and oyster shells for the indigenous people.
