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.
