Draw One-Point Perspective

In perspective drawing, every set of parallel lines has its own vanishing point. Don't panic. We can keep it simple. To draw one-point perspective, we arrange our subject so that one set of lines has a vanishing point right in front of us, and the set at right-angles goes out to infinity on each side - parallel, either straight up or straight across. See the railway sleepers, how they stay parallel, straight across in front of us? And the fenceposts stay perpendicular (straight up-and-down). The railway lines and fence wire move away from us, to the one vanishing point in the distance.
