The selvedge (also spelled selvage) is the reinforced left and right edge of a hand-knotted rug. It runs vertically along the long sides of the rug, from the top fringe to the bottom fringe, and is formed by the weft threads wrapping back around the outermost warp threads to lock the structure in place.

How selvedges are constructed:

  • During weaving, the weft threads pass through the warp threads across the full width of the rug
  • At the left and right edges, instead of stopping, the weft wraps around the outermost warp threads before reversing direction
  • This wrapping creates a thicker, denser edge that resists wear
  • In some traditions, additional selvedge-cord wrapping is added after the rug is woven, wool yarn wrapped tightly around the edge for further reinforcement
  • Selvedges may be single-cord (the simplest form) or multi-cord/braided (more durable, common in higher-grade Persian and Turkish workshop pieces)

Why selvedges matter:

  • Structural integrity, the selvedge is what holds the sides of the rug together. A damaged selvedge will, over time, allow the foundation to unravel and the pile knots to loosen.
  • Wear point, selvedges are one of the most common points of wear in older rugs. They take abuse from foot traffic, furniture legs, and edge-to-edge contact with walls or other rugs.
  • Indicator of construction quality, well-made workshop rugs have neat, even, tightly-wrapped selvedges; poorly made rugs may have loose, irregular, or damaged selvedges even when new
  • Attribution clue, the style of selvedge (single-cord, multi-cord, color choices, wrapping pattern) varies by region and can help identify a rug's origin

Selvedge variations across rug traditions:

  • Persian workshop rugs, typically single or double cotton/wool cord, tightly wrapped, neat and uniform
  • Anatolian (Turkish) rugs, often have multiple wool selvedge cords wrapped in distinctive patterns, sometimes in contrasting colors
  • Tribal Persian and Caucasian rugs, varying styles, often with distinctive regional touches
  • Turkmen rugs, frequently have goat-hair selvedges or characteristic dark-wool wrapping

Selvedge repair is one of the most common rug restoration services. A skilled repair technician can re-wrap a damaged selvedge to extend the rug's life and prevent unraveling. This is generally an affordable repair and a good investment for any rug showing edge wear.
