Single line! We wanted to separate rubbish into various rubbish types - writing/maps/drawings/photographs/collages and align each one of them to its own horizon line
(with an overlap)
Yes chalk liner would be perfect. I love that thing. So cool.
I think we better leave the staples in, its a nice way of recording what has been on there before - since the rubbish bags did not last, despite our instructive note :( oh well. I’m sure there are many other ways we can summarise in a couple of weeks. Maybe its a restyling of all the staples in the wall. Take them out and staple them back on again in an orderly fashion???
