Warping a Treadle Loom — Measuring, Beaming, and Threading Warp for Broadcloth
Warping is the long, meticulous process of preparing a horizontal treadle loom for weaving. Every thread of the warp — the lengthwise threads that form the skeleton of the cloth — must be measured to exact length, wound onto the warp beam in perfect tension, drawn through the heddle eyes in the correct sequence, and sleyed through the reed at the proper spacing. A single error in threading or a single crossed thread will produce a visible flaw in every centimetre of cloth woven afterwards. Medieval weavers warped their looms with thousands of threads for broadcloth — a full warp for a standard bolt might contain 2,000 to 4,000 individual threads, each one measured, counted, and threaded by hand. The process could take a full day or more, but the quality of the warping determined the quality of every bolt of cloth the loom would produce. This blueprint covers the complete warping sequence from winding the warp on a warping board through beaming, threading heddles, and sleying the reed.

Calculate the warp
Calculate the warp
Determine the total number of warp threads needed. This depends on three factors: the finished cloth width (typically 150-180 cm for broadcloth), the sett (threads per centimetre — usually 8-12 for medium wool), and the selvedge allowance. A broadcloth at 10 threads per centimetre and 160 cm width requires 1,600 warp threads. Add 10% extra length for loom waste — the untensioned thread at each end that cannot be woven.

Prepare the yarn
Prepare the yarn
The warp yarn must be stronger than the weft — it endures constant tension, friction from the heddles and reed, and the repeated lifting and dropping of the shed. Use well-spun, tightly twisted yarn. Wind the yarn onto bobbins or cones for easy dispensing during warping.

Set up the warping board
Set up the warping board
Mount the warping board on a wall or prop it upright. A warping board is a flat wooden frame with a series of pegs arranged in a zigzag pattern. The yarn is wound around the pegs in a continuous path, and the distance between the first and last peg determines the warp length. Adjust the peg positions to set the correct warp length for your bolt.

Wind the warp threads
Wind the warp threads
Tie the yarn end to the first peg and wind it around the zigzag path to the last peg and back, counting each thread carefully. At the cross pegs — two pegs near the beginning of the path — alternate the thread over and under on each pass to create a cross. This cross keeps every thread in order and prevents tangles when the warp is transferred to the loom.

Tie the cross and chain the warp
Tie the cross and chain the warp
When all threads are wound, tie the cross firmly with contrasting cord — two ties, one on each side of the cross. Then chain the warp off the board like crocheting with your hands: reach through the loop at the end, grab the next section of warp, pull it through to form a new loop, and repeat. This prevents tangling during transport to the loom.

Prepare the loom
Prepare the loom
The horizontal treadle loom consists of a sturdy timber frame with a warp beam at the back, a cloth beam at the front, two or more shafts with heddles hanging from them, a reed mounted in a beater, and foot treadles below. Check that all parts move freely — shafts rise and fall smoothly, the beater swings without binding, and both beams turn and lock.

Beam the warp
Beam the warp
Spread the chained warp across the back beam of the loom and lash its loop end to the warp beam rod. With an assistant holding tension at the front, wind the warp onto the warp beam, inserting stiff paper or thin wooden sticks between each layer to keep the threads at even tension. Wind slowly and evenly — uneven winding causes loose and tight threads that make weaving impossible.

Thread the heddles
Thread the heddles
Sit at the front of the loom. Working from the cross (which keeps threads in order), draw each warp thread through the eye of a heddle on the correct shaft. For plain weave: thread 1 goes through shaft 1, thread 2 through shaft 2, thread 1 through shaft 1, and so on alternating. For twill weave: the threading follows a 1-2-3-4 repeat across four shafts. Each heddle eye must hold exactly one thread.

Sley the reed
Sley the reed
After all threads are through the heddles, draw them through the dents (gaps) of the reed using a reed hook. The reed determines the spacing of the warp threads and the width of the cloth. For broadcloth at 10 ends per centimetre with a 10-dent reed, place one thread in each dent. For finer cloth, place two threads per dent in a coarser reed.

Tie onto the cloth beam
Tie onto the cloth beam
Divide the warp threads at the front of the loom into small groups of 15-20 threads each. Tie each group to the cloth beam rod using a surgeon's knot or similar adjustable knot. Work across the full width, then go back and adjust each tie until the tension is absolutely even across the entire warp. This is the most critical moment — uneven tension here means uneven cloth.

Tie up the treadles
Tie up the treadles
Connect each treadle to the correct shaft using cords. For plain weave with two shafts: left treadle lifts shaft 1, right treadle lifts shaft 2. For four-shaft twill: each treadle lifts a different combination of shafts. Test each treadle — pressing it should cleanly raise or lower the correct shafts and open a clear shed between the warp threads.

Check the shed
Check the shed
Press each treadle in turn and check that the shed — the opening between the raised and lowered warp threads — is clean and even. No threads should be caught on the wrong side. The shuttle must be able to pass through without snagging. If any threads are misthreaded, correct them now before weaving begins.

Weave a test header
Weave a test header
Weave 5-10 centimetres of scrap yarn through the warp as a test header. This evens out the tension, tests the treadling sequence, and reveals any threading errors. Check the weave: the pattern should be regular, the selvedges even, and no threads crossed or skipped. Correct any errors before proceeding with the actual cloth.

The loom is ready
The loom is ready
With the test header woven and all errors corrected, the loom is fully warped and ready for weaving. The warp threads are under even tension, threaded in the correct sequence through the heddles and reed, and the shed opens cleanly. From here, the weaver loads the shuttle with weft yarn and begins the rhythmic work of weaving — treadle, throw, beat — that will eventually produce a bolt of broadcloth.
