I do remember doing it and it been a big thing at Gisborne intermediate.
We had to plan it etc.
I remember thinking it was weird that we made our skin yellow, like the Simpsons.
It was important to me to scratch out the shape of my green stone I always wore at the time.
The half and half colors back ground seemed to be the thing and then scratching out shapes.
When ever i have looked at it as a adult it makes me remember my greenstone.
It was my first and it holds a special place for me.
I don't think I have improved in regards to my artistic ability since then.
