There was a time I used only spray paint for my work.
As my projects grew larger, I discovered other materials and techniques.
For this wall I used 12 five Gallon buckets of latex wall paint.
I sketched right on the wall and then I filled everything in with a roller.
Then I used only a few spray cans for the outlines and small details.
Approximately 7m x 20m or 23 x 66 feet
Got one of those boring ugly walls that really could use some color ...?
