I accidentally made the center line on this so dark that instead of drawing right on top of the construction drawing, I put it behind a second sheet and used it underneath - leaving almost no erasing. Not the way it's supposed to be done, I know, but I figured better to do it that way than ruin my paper by trying to erase it.
