The best place to see them is on aerial photographs at sufficient distance from Earth to show the distinct regularly associated with bands of cloud which are in turn associated with frontal systems. Seen from above in this way, the edge, where the cloud band dissipates out at its highest level of outflow, can give the illusion of the whole cloud layer or ribbon consisting of a homogeneous mass throughout, whereas in fact what is concealed underneath from that vantage point is a whole lot of complexity, with several layers of cloud, sometimes separated, often merged, concealed from view.
