Antique rug restoration

Three rules before touching anything

Minimal intervention. What is moving is stabilised first — an open edge, a running fringe, a tear that is spreading — and the work stops there for as long as nothing is under threat. A rug that has come through a century does not need to be made new again; it needs not to lose any more.

Reversibility. Anything added must be removable without taking any of the original with it: stitches, never glue; added threads, never iron-on backing. The restorer who comes after us must be able to undo our work without damaging the rug.

Compatibility of materials. Wool on wool, cotton on cotton, silk on silk, and dyes that age at the same rate as those of the rug. A synthetic thread does not move when everything around it does: after a few years, it stands out like a scar.

Restore or conserve?

The debate is an old one and it has no single answer. To conserve is to halt the deterioration and leave legible what time has done: the wear, the losses, the repairs of previous generations. To restore is to re-establish the design and the use, even at the cost of erasing part of that history.

The choice depends on what the rug is going to become. A piece meant to be laid down and walked on must be structurally complete: selvedges, fringes, foundation. A piece meant for the wall, the display case or simple conservation can remain incomplete, provided it is stabilised.

We ask the question before the quote, because it changes the whole job — and because it belongs to the owner, not to the workshop.

Relining

When a rug no longer holds together on its own — a tired foundation, wool gone fragile, a fabric tearing under its own weight — a textile support is applied to the back. The rug is no longer carried by its own foundation but by that cloth, sewn with supple stitches that let it work along with the rug.

A well-made relining does not stiffen the rug and comes off without damage. A glued relining, by contrast, is permanent: the glue penetrates the foundation, hardens it, and makes it snap at the folds. It is one of the interventions we most often remove from the pieces that reach us.

What destroys value

A badly restored antique rug is worth less than a damaged antique rug. The list of the damage is always the same: synthetic wool used to re-knot, colourants that will not age as the vegetable dyes do, industrial fringes added on, overcasting laid so tight that the edge ripples, pile shaved too short to hide a join, abrash corrected with dye.

The abrash, precisely, those horizontal bands of slightly different tone, is the signature of a change of dye bath, and therefore an argument for authenticity. It is not erased. In the same way, a well-made old repair is part of the object: it is conserved, it is not replaced on the grounds that it shows.

One last useful marker: aniline colourants appear in Turkey around 1882, and their presence dates a rug to after 1870-1880. Knowing which world of dyeing one is in avoids irreversible mistakes — and makes it possible to tell an owner honestly what he actually has in his hands.

Documenting it, and handing that over with the rug

Every antique piece is photographed before, during and after, face and back, with the detail of the areas treated and the nature of the materials used. That documentation goes away with the rug.

It serves three times over: for your insurer, for a later appraisal, and for the next workshop to open the file. An undocumented restoration is a restoration that will one day have to be guessed at.
