Rug Side Cord and Edge Repair Explained

Along with the fringe at the ends, a rug’s long sides have a finished edge — the side cord or selvedge — that quietly does structural work. When those sides start to fray or unravel, it’s easy to overlook, but like fringe damage, it threatens the rug. Understanding rug edge repair means knowing what the side cord is (the wrapped, bound edge of the foundation), why it matters, and how it’s repaired when it wears. Catching side damage early keeps the rug from coming apart. Here’s rug side cord and edge repair explained — part of proper rug care.

What the Side Cord (Selvedge) Is

To understand rug side cord repair, first know what the sides are. Just as the fringe finishes and comes from the ends of a rug, the two long sides of a rug have a finished edge called the selvedge or side cord. On a handmade rug, the outermost edge of the foundation along each side is bound and reinforced — typically the edge warp threads are wrapped or overcast with yarn (wool or cotton), sometimes over a cord, creating a firm, finished selvedge repair rug edge (the ‘side finish’). This wrapped side cord binds the edge of the foundation together and protects it, keeping the outer edge of the rug from fraying and the weave from unraveling at the sides. It’s the long-side counterpart to the fringe at the ends: both are finished edges that protect and contain the rug’s foundation. Like the fringe, the side finish is structural, not merely decorative — it holds the rug’s edge together. So when people say a rug’s ‘sides’ are going, they mean this selvedge/side cord: the bound edge that finishes and protects each long side of the rug. Knowing what it is makes clear why keeping it intact matters — it’s part of what holds the rug’s structure at the edges. The Metropolitan Museum of Art describes the selvedge as the finished, reinforced side edge of a woven textile.

Why Sides Fray, and Why It Matters

Now, rug sides unraveling — why it happens and why to address it. The side cord takes wear: the edges of a rug are exposed and get scuffed, walked on, bumped by vacuums and furniture, chewed by pets, and worn by age, so over time the wrapping yarn of the selvedge frays, wears through, or comes loose, and the side finish starts to unravel. Once the side wrapping goes, the edge of the foundation is exposed and unprotected — and just like with fringe, this lets the damage progress: the outer edge can begin to fray and the outermost warps and knots along the side can loosen and unravel, so the rug can start coming apart from the side inward, losing its edge and width. A small unraveling side becomes a bigger structural problem. This is why side/edge damage matters and shouldn’t be ignored: the selvedge is protecting the rug’s edge, and when it fails, the rug is vulnerable at the sides. As with fringe, catching it early — re-securing the side finish while the damage is small — is far simpler than repairing an edge that has unraveled into the field. So fraying, worn, or loose sides are a signal to repair, not overlook. The Carpet and Rug Institute notes edge/side damage can lead to progressive unraveling if not repaired.

How Edge Repair Is Done

The good news is that overcasting rug edge repair is a standard, effective restoration that re-secures the sides. Depending on the condition, a specialist has options: re-wrapping/overcasting the edge — the most common repair, where the worn or missing side wrapping is redone, wrapping (overcasting) the edge warps with matching yarn to rebuild the selvedge/side cord and re-bind the edge, restoring the finished, protected side; rebuilding the side cord — if there’s an underlying cord or the edge structure is damaged, the specialist rebuilds or replaces the side cord and re-wraps it; and edge/foundation repair — if the unraveling has progressed into the rug (lost edge warps or knots), the specialist first repairs the edge foundation and any lost knots, then re-secures the side finish, a more involved restoration. In all cases, the work is done by hand with matching materials to restore a sound, finished edge that matches the rug. The result is a re-secured side that stops the unraveling and protects the rug’s edge. As with fringe, early edge repair (just re-wrapping a worn side) is simple and affordable, while a badly unraveled side needs more work — so address side damage promptly. If your rug’s sides are fraying or unraveling, have the edge repaired. When needed, our specialists can re-wrap and rebuild rug edges. The IICRC notes side/edge repair should match the rug’s original edge finish.

A rug’s sides — the selvedge or side cord — are the finished, wrapped edges that bind and protect the outer edge of the foundation, the long-side counterpart to the fringe. They’re structural, not decorative. When the side wrapping frays, wears through, or comes loose from use and age, the edge is exposed and, like damaged fringe, the rug can start unraveling from the side inward, losing its edge and width. Edge repair re-secures the side: a specialist re-wraps (overcasts) or rebuilds the side cord by hand with matching materials, repairing the edge foundation first if the unraveling has progressed. As with fringe, catching side damage early keeps the repair simple. Fraying sides are a signal to repair, protecting the whole rug.
