I invite people to draw, it's always nice to give in exchange ..... been keen to use carbon copy paper this is the test.
It's pretty messy on the hands, gives beautiful carbon duplicates from linear drawing, doesn't work with the fluro Braille bumps that pushes too much carbon through just giving the dot grain of the eco paper.
I will aim to do new site specific carbon copy stretch about 6m long to wrap the entrance of stores tunnel.
