How to weave a chair seat with rope

The short answer

Wrap the rope around the front and back rails, strand tight against strand, to make the warp. Then weave from side to side, over and under the warp, around the side rails, pushing every row tight. If the seat is wider at the front, cover the extra width at the front corners first. Start and end underneath, and make every join there too.

On Danish design classics the rope is flag halyard, a braided line made to take strain for years. That’s what we weave, so this guide is written for it.

Which rope?

Flag halyard is the rope used on chairs like Wegner’s Flag Halyard Chair and Circle Chair and Kjærholm’s PK25. The one we use has a nylon core inside two layers of braided linen. It’s strong, it keeps its shape, and it’s comfortable to sit on. It comes in natural and black.

Jute and paracord can be woven in the same way, and people often ask about them. They behave differently, though: they give and wear in their own ways. If you use them, weave a few test rows and check the tension before you commit to the whole seat.

How much flag halyard you need

The amounts we measure out in the workshop for chairs we weave often. Buy it in one length if you can: fewer joins, cleaner seat.

What you need

Materials

  • Flag halyard in the thickness of the old seat, usually 6 mm. See the table for amounts.

Tools

  • A good knife
  • Clamps to hold the tension when you stop.
  • A weaving needle or a flat stick, for the last rows.
  • Tape around the cut ends, so they don’t fray while you work.
  • A tape measure

How to weave a rope seat in seven steps

This is the classic woven rope seat on a frame with four rails. Some chairs are only wrapped, with the rope wound tight side by side and no weave; weave yours the way it was made.

  1. Step 1: Photograph the old seat

    From above and below: which rails the rope goes around, how the weave goes over and under, and where the ends are hidden. It’s your pattern, and it tells you whether the seat is woven or only wrapped.

  2. Step 2: Prepare the frame

    Remove the old rope, glue any loose joints and smooth sharp edges on the rails. The rope bends hard around the rails; a sharp edge wears through it.

  3. Step 3: Start underneath and square the seat

    Fasten the start of the rope on the underside, where it’s hidden by the seat later. If the front rail is longer than the back, cover the extra width at each front corner with short warp lengths from the front rail to the side rails, or fan the warp the way the old seat did. Your photos show which.

  4. Step 4: Wrap the warp

    Wrap the rope around the front and back rails, going front to back, each strand tight against the last. Keep them parallel and don’t let them cross. Pull every wrap equally tight; a slack strand now becomes a dip in the seat.

  5. Step 5: Weave from side to side

    Now weave across the warp: over and under, in the pattern of the old seat, around the side rail, and back. Push each row tight against the last, so the rows stay straight and close.

  6. Step 6: Join underneath

    When you need more rope, make the join on the underside, never on top. Even better: buy the whole length in one piece and avoid joins altogether.

  7. Step 7: Finish without visible knots

    The last rows are tight; use the needle or a flat stick to get the rope through. Fasten the end on the underside, worked in under the strands so it can’t pull loose, and check the seat from above: straight rows, even tension, no knots in sight.

Mistakes we often see

  • Buying too little

    A short roll means extra joins. Check the table, and add a few metres.

  • Uneven tension

    Some strands tight, some slack: the seat sits unevenly and wears faster. Keep a steady pull from start to finish.

  • Crossed strands in the warp

    A crossed strand shows through the whole weave. Lay each strand flat beside the last.

  • Knots on top

    They press into whoever sits there and wear the rope. Every start, join and end goes underneath.

  • Working with cold, stiff rope

    Let the halyard rest indoors for a few days first.

Questions we get a lot

What rope is best for a chair seat?

For a seat that stays tight and lasts, flag halyard: a braided line made to take strain. It’s what Danish designers used, and what we weave.

Can I weave a chair seat with jute or paracord?

The method is the same, but the result isn’t. Weave a few test rows and check the tension before you do the whole seat.

How much rope do I need for a chair seat?

From about 36 m for a small seat to about 225 m for Wegner’s Flag Halyard Chair. See the table above for classic chairs.

Is flag halyard hard to weave?

It’s simple to learn, but it’s physical work, and the tension takes practice. We rate it between beginner and advanced.
