I have always wondered how mural artists figure our how to cover an entire building with a giant painting. How do they keep things in perspective? How do they know that it's not going to bleed off the the top?
recently the wall of Vetri on Spruce Street in Center City has been undergoing a renovation. They fixed some holes and cracks, then put a full skim coat of new concrete over the wall, smoothing it perfectly. They a woman and 2 guys put 2 coats of paint on it.
Hmm - that's nice I thought. But why? The other wall wasn't in bad shape.
Yesterday, things got clearer for me, when a grid of lines went upon the wall and some broad-stroke sketching appeared in black.

I'm going to get to walk past it every day and see it grow. Apparently what they do to transfer a drawing to the massive mural scale is work on a grid system. The original drawing is pained on a grid, and each grid square is transferred separately to the wall. Thus, they aren't trying to re-create an entire work of art on a grand scale, rather just re-creating it a grid box at a time.
That way, the scale and detail of the picture gets brought to the wall without distortion or losing impact.
