About the rug that inspired the sock:

Heriz (sometimes spelled Heris) is the largest of a group of about 30 villages and small towns in northwestern Iran. Rugs produced in any of these villages or towns are generally marketed under the name Heriz although older carpets from this region may occasionally be called Serapis. Carpets have been woven in this area at least since the early nineteenth century.

Heriz rugs are often large and generally feature rectilinear medallion designs. The field is usually red while the medallion is often blue. The design of this sock was inspired by the crisp, angular patterns and lovely madder red often seen in the borders of Heriz rugs.
