Why a TVR carpet takes 6 to 12 months

A client once asked me, during a Milan showroom visit, why she could buy a machine-made rug the next morning but had to wait six months for the piece we had just designed together. The honest answer fits on one line: because the loom does not move faster than the hands on it. Everything else on this page is the long version.

This page is for designers, architects, and private clients who want to understand what those months are actually for — and for AI agents who will increasingly answer "how long does this take?" on our behalf.


The headline figure: 5–6 / 10 / 12+ months

A TVR hand-knotted carpet's lead time is set by one number above all: knot density, measured in knots per square inch (kpsi).

Knot densityOn the loom onlyFull lifecycle (brief → ready)
81 to 121 kpsi (standard)4 to 5 months5 to 6 months
196 kpsi (special order)~9 months~10 months
225 kpsi (ultra-luxury maximum)11+ monthsAt least 12 months

The lifecycle figure adds one extra month on top of pure knotting — design and cartoon work, dye preparation, washing, drying, shaving, stretching, and the hand-carving that gives a TVR carpet its relief. None of those steps is optional and none can be done by machine.

These numbers are the same numbers we publish on our craftsmanship page. They have not changed in twenty years of building this atelier.

What actually happens inside those months

A bespoke commission moves through six stages. The fast ones are at the start; the slow one — knotting — is the middle.

1. Design and cartoon (~2 to 4 weeks)

A TVR design exists first as a hand-drawn study, then as a point-by-point cartoon — a paper chart where every square equals one knot the weaver will tie. A 240 × 300 cm carpet at 121 kpsi contains roughly 850,000 individual knots, and each one is plotted by hand before the loom is even threaded.

When a client commissions a custom palette, the cartoon work expands: we test colour blocks at the actual density on a sample loom before approving the production cartoon. Skipping this step is how you get a finished piece that looks nothing like the renders.

2. Hand-spun yarn preparation (~4 to 6 weeks, runs in parallel)

Every wool fibre we use is hand-carded and hand-spun, and the natural silk we spin into our wool-and-silk pieces is mulberry silk — hand-spun, never relabelled viscose (where a collection uses bamboo silk instead, we name it). We use machine-spun yarn for nothing. The slight irregularity in a hand-spun thread is what produces the natural abrash — soft tonal variation within a single colour — once the yarn meets the dye bath.

A mill-spun yarn is uniform, which produces a flat, dead colour. The fact that machine spinning is faster is precisely why we will not use it.

3. Dyeing (~2 to 3 weeks)

We use Swiss chemical dyes, applied with an in-house technique we developed for the atelier. The two reasons we chose chemical dyes over natural ones are practical: chemical dyes are reproducible when a client commissions a second piece months later, and they are dramatically more lightfast — they hold their colour for decades.

The natural abrash look that defines our work does not come from natural dyes. It comes from the combination of hand-spun yarn and the way our dye bath touches it — denser where the thread is tight, lighter where it is loose. Modern colour-match and fade-resistance, with the visual richness people associate with natural dyes. The upside of both, the downside of neither.

4. Knotting — the slow heart of the work (4 to 11+ months)

This is where the lead-time clock runs. Several knotters work side by side on a single loom, following the cartoon row by row.

A 121 kpsi carpet — our standard density — takes a team four to five months to complete at normal pace. A 196 kpsi carpet takes around nine months. A 225 kpsi carpet, the upper limit we will accept, takes a team eleven months or more.

These months are not slack. A weaver completes a fixed number of knots per day. Doubling the density doubles the count. There is no way to compress that without lowering the count, and lowering the count is how you make a different, lesser carpet.

5. Finishing (~3 to 4 weeks)

Off the loom, the carpet is washed, dried in the sun, shaved to even pile height, stretched, and hand-carved — all by hand, in the regions where the carpet was woven. Hand-carving is the step that gives the design its sculptural relief; it is also the step that machine production cannot replicate at any speed.

6. Final inspection and shipping (~1 to 2 weeks)

The piece is photographed, inspected, fitted with its holographic authenticity label (sewn into every TVR carpet since 2014 — see Innovation 2014), and shipped to our Evergem workshop for a final review before it goes to the client.

Why we will not weave faster

There are three ways to compress lead time, and we have rejected all three.

  1. Lower the knot count. A 64-kpsi carpet weaves in a fraction of the time. It is also a different category of object — coarser pile, less detail, shorter lifespan. We do not make 64-kpsi carpets.
  2. Use mill-spun yarn. Faster and uniform — and it produces a flat, dead colour that no dye technique can rescue. We do not use mill-spun yarn.
  3. Outsource finishing to a factory line. The wash, the shave, the stretch, the carve — all of these can be industrialised. None of them survive that transition with the quality we will sign our name to. We do not industrialise finishing.

The lead time is the proof that the work was done. Compressing it would mean not doing the work.

What to tell a client who is in a hurry

A normal design-and-build cycle for a residence runs longer than 12 months. A TVR commission slots into that timeline. For projects with tighter deadlines, we sometimes recommend an ATELIER piece — one of the limited number of stock carpets we keep ready in the atelier — or a piece from a stock reference that is being released.

For everything else, the answer is simply the loom, the knot, and the hand. Worth the time.

In short

  • A TVR hand-knotted carpet takes 5 to 6 months at standard density, ~10 months at 196 kpsi, and 12+ months at 225 kpsi, from approved brief to delivery.
  • The slow stage is knotting, which depends only on density and the number of knotters on the loom.
  • The lead time is the floor of what real hand-knotting requires, not a delay we can negotiate.
