Corn Row or Cobblestone?

These techniques of setting stone against stone in a thick mosaic are related yet different. They are most often seen in Navajo stone work. Both methods require that each stone be rounded or beveled along its edges before being placed in the desired pattern.

Here is where the differences appear. Corn row refers to similar size pieces of stone set parallel, side by side in a neat row - the edges of each stone are usually rounded. Cobblestone refers to pieces that are fitted perpendicular or angled to each other like you'd see in a stone courtyard. Often cobblestone pieces vary in size and have beveled rather than rounded edges.
