Rug Overcasting & Stitching.

Selvedges

The selvedge is the long edge of a rug, finished by wrapping the warp threads with a contrasting yarn. When it breaks, the foundation begins to unravel. Selvedge repair re-secures the edge and stops the damage.

Ends

The two short ends are where fringes meet the rug body. End damage shows as missing pile near the fringes or fraying knots. We rebuild the structural threads first, then re-stitch the surface.

Why now

Foundation damage spreads. A small split today is a large hole in six months. Fixed early, the repair is fast and inexpensive — fixed late, it becomes a reweave.

Overcasting is hand stitching around a rug's perimeter using matched wool yarn. It's the original method — the same technique used by the weavers who made the rug, often a hundred or more years ago. The resulting edge is structurally part of the rug, not a separate added component, and it's nearly invisible from normal viewing distance.

The alternative is machine binding — a wide cotton or synthetic tape sewn around the edge by industrial machine. Machine binding is faster and cheaper. It looks acceptable on modern hand-tufted and machine-made rugs. But on a hand-knotted oriental piece, machine binding looks like exactly what it is: a foreign attachment to a hand-made rug. Visible, awkward, and a value reducer for any piece that might later be appraised.

We use hand overcasting on hand-knotted oriental rugs whenever the rug is worth the investment. The work is slow — a typical 8×10 piece takes 8–16 hours of hand stitching, depending on the rug's edge complexity. The yarn is matched to the original wool color and gauge, which sometimes requires hand-dyeing.

Cost runs $8–$15 per linear foot for hand overcasting versus $4–$6 for machine binding. For an 8×10 area rug (about 36 linear feet of edge), that's typically a $200–$300 difference. On any rug appraising above $3,000, hand overcasting is the right answer. Below that, machine binding is usually fine.

The edges and ends take the most stress on any rug, and they're usually the first place damage appears. Caught early, overcasting is quick, inexpensive, and prevents a much larger repair down the line.

Look for a selvedge that has come loose or is hanging away from the body, short ends where the knots are starting to slip past the fringe, or any spot where the pale foundation threads are showing through. Each of these is the foundation beginning to open up, and each gets worse — and more expensive — the longer it waits.

• Knots slipping or unraveling at the short ends
• Exposed warp or weft threads showing through the pile
• Any fraying that grows week to week — a sign to act now
