About the rugs that inspired the socks:
Uşak (sometimes spelled Ushak) is a city in eastern Turkey. Rugs have been made there since at least the fifteenth century. Because rugs have been produced here for centuries, and because eastern Turkey is fairly close to Europe, many of the carpets first brought to Europe were from this area.
Uşak rugs (and Turkish rugs in general) often use a different color palette than do Persian rugs. They use less blue and red and more brown, yellow, and rust. Uşak rugs combine this color scheme with a characteristic floral motif. The color and stylized floral design of this sock reflect this distinctive style.
