Pencil lines that will become lettering

A few years ago I had a disagreement with some drawing researchers about erasing mistakes. They said all lines are important and should always be kept. I don’t think we were talking about the same kinds of drawings, or if they draw at all.

Yesterday I was drawing with an eraser, adding highlights not removing mistakes. That reminded me of the odd discussion. Today I’ve been moving lettering around. Lots of lines have been changing position. I’m glad I’m not forced to keep all the previous versions as it would’ve been a solid block of lines by now.
