These drawings were outlined in pen on tracing paper over a printout of a Cα trace of the atomic coordinates, and shaded with colored pencil or pastels; they preserved positions, smoothed the backbone path, and incorporated small local shifts to disambiguate the visual appearance. As well as the triose isomerase ribbon drawing at the right, other hand-drawn examples depicted prealbumin, flavodoxin, and Cu,Zn superoxide dismutase.
