Measure the Repeat on Finished Cloth: What the Mill and Your Marker Agree On

Before the lay is released, the mill’s repeat data and your marker plan must describe one thing only: the repeat measured on the finished, relaxed cloth, in both directions, at the width positions where the pieces will actually sit. The weaving specification, the design artwork and the greige record are references, never cutting numbers, because finishing moves check lines. Both documents should agree on four points before spreading starts: the measured lengthwise repeat, the measured crosswise repeat, the datum line both parties count from, and the ranked list of seams that must match. When those four figures are shared, the extra metreage stops being an argument and becomes a written line in the order, priced and planned like any other cost.

The repeat that counts is measured on finished cloth, not copied from the loom sheet

A check’s repeat is born at the loom, but it is not preserved through everything that happens afterwards. Scouring, milling, washing, stretching, decating, calendering and simple relaxation each nudge the spacing of the lines, and woolen cloth in particular keeps moving until it has rested. The figure on the weaving sheet therefore describes a cloth that no longer exists by the time the roll reaches your cutting table. This is why the mill’s data must be restated as finished-cloth data, taken after the last wet and dry processing stage and after the roll has cooled and relaxed.

The distinction sounds pedantic until a marker fails. If the marker was built on the greige repeat and finishing shortened the cloth, every placement that depended on a whole number of repeats drifts a little, and the drift compounds down a lay of many plies. Pockets land a fraction off the fronts, and the fault repeats on every garment in the lay. Anyone who wants to see how much treatment a length of cloth passes through can read about textile manufacturing and finishing, and will notice that the finishing stage is exactly where dimensional change concentrates. So ask the mill one specific question: what is the repeat of this cloth now, as it will arrive, and when was it last measured? If the answer comes back as a design figure or a greige record, the marker is not ready to be released. Treat the plan as provisional until someone has put a tape on the cloth itself.

Measure the repeat the same way every time, and record where you measured

Reliable repeat data comes from a fixed procedure, not from a quick glance at a folded corner. Lay the sample from the roll flat on a table and let it relax, because cloth measured under tension will lie about itself. Identify the dominant line of the check, the one a stranger would pick without being told, and call that the datum. Then measure along the length of the cloth, close to one selvedge, from that datum line to the tenth identical line below it, and divide the distance by ten. Repeating the reading near the other selvedge and at the center of the width gives three averages for the lengthwise repeat.

For the crosswise repeat, work across the width instead: from a dominant vertical line to the tenth identical vertical line, measured at several points along the roll, at the front, the middle and the back. Ten repeats rather than one is the whole point, because local distortion, a slub, a stretched pass through the tenter frame, gets smoothed by the average instead of being mistaken for the pattern itself. Every reading goes on a record sheet with the roll number, the dye lot, the date and the name of the person who measured, and each reading is tied to the place it was taken, left selvedge, center, right selvedge, so a later disagreement can be traced to its source. The average of those readings becomes the cutting repeat that both the mill data and the marker plan must quote. A number without a method behind it is only an opinion, and opinions do not survive contact with a lay of checked cloth.

Rank the match: which seams must agree and which are allowed to drift

Matching everything perfectly is possible only in theory, because every upgrade from drift allowed to must match costs length in the marker. The professional answer is a ranked list, agreed before the marker maker starts. The center front and any front opening stand first: the two halves of a coat face each other at conversational distance, and a mismatched bar across the closure reads as a fault to everyone, not only to tailors. Patch pockets and pocket flanks stand second, because they sit on top of the fronts and the check is expected to continue through them without interruption. Collars and lapels stand third: the pattern should roll over the break and meet the body without a visible jump, which constrains where the undercollar and topcollar pieces may be cut. Side seams, underarm seams and most internal seams stand last, where a controlled drift is commonly accepted by agreement.

The ranking decides marker economics. Fronts and pockets demand whole-repeat placement and, on many checks, a one-way lay, since an uneven or half-drop construction will not tolerate turned pieces. Whether the check is balanced, mirrored or half-drop is a property of the weave, so it is worth naming the construction precisely, herringbone, houndstooth, gunclub or plain block, before anyone promises a match, because two checks of similar scale can behave completely differently at a seam. A ranked list in writing also protects the cutter in a dispute: if the order says the side seams may drift and the customer later complains about the side seams, the document settles the argument. Match rank, allowance and tolerance belong to one conversation, held before cutting, not after.

The matching allowance belongs in the order, not in a late phone call

On plain cloth, cutting loss is the exception that quality control chases. On checked cloth the logic inverts: extra consumption for matching is the normal condition of the material, present in every lay, on every style, for as long as the check runs. Treating that extra metreage as a surprise, discovered only when the marker is plotted, guarantees a bad outcome for one side of the deal. The remedy is dull and effective: the allowance, expressed as a percentage of base consumption and derived from the agreed matching strategy, is written into the purchase order at booking stage, together with the repeat basis it was calculated from.

Writing the number down changes behaviour on both sides. The mill prices the order on realistic consumption instead of a theoretical minimum, and reserves continuity of lot accordingly. The cutter cannot be squeezed later into matching on a metreage that was never booked, and the garment maker cannot be accused of padding the quantity. The clause does not need to be long. It should name the finished-cloth repeat as the calculation basis, attach the ranked match list, state the allowance that both parties accepted from that strategy, and assign the duty of re-measurement on arrival, which is the next subject. What it must never be is a verbal figure remembered differently by each side. A matching allowance that lives in a phone call is not an allowance; it is a dispute with a delay attached.

Every arrival is re-measured at the cutting floor, roll by roll

The mill’s repeat report is a claim. The cutting floor’s tape measure is the fact the lay will be built on, so the duty of re-measurement belongs to the receiver, on every batch, not once at the start of a relationship. Mills change finishing contractors, retune tenter frames and adjust recipes; a repeat that held for two seasons can move in a third. When a delivery arrives, the cutting floor checks the rolls against the order basis: the same ten-repeat measurement, at the same named positions, recorded against the same roll numbers. Sampling does not need to be heavy, but it needs to be honest, spread across the delivery rather than taken from the top roll of the pallet.

If the arrival measurement disagrees with the booked repeat, the marker is held and re-planned before a single ply is spread, and the difference goes back to the mill while the cloth is still theirs to answer for. That is the practical value of the receiving record: it converts a vague complaint about appearance into a documented dimensional claim, with method and readings attached. It also protects the mill from false claims, because the record shows exactly where and how each figure was taken. Reliance on a certificate in a filing cabinet, by contrast, leaves the cutting room to discover the truth mid-lay, when the discovery is expensive and nobody’s fault in particular. Re-measurement is not distrust; it is the receiving half of the same measurement procedure the order was written on.

Repeats and usable width must reconcile across the full width of the lay

The lengthwise repeat gets all the attention, but the crosswise repeat decides what can be paired, and it has to reconcile with usable width, selvedge to selvedge minus the dead edge. Count how many whole repeats fit across that usable width. If the count comes out whole, left and right fronts can be cut side by side in register, and a pocket lifted from one width position will agree with a front cut at another. If the count leaves a fraction, that fractional strip near the selvedge belongs to no repeat at all: pieces cut from it will never match the body, however careful the marker. On small checks the fraction is narrow enough to lose in the edge trim; on bold checks it is a planning constraint that shapes the entire marker.

Width is also where cloth faults surface first. If the repeat measures differently near the two selvedges, or the vertical lines walk out of square across the width, no marker discipline will rescue the match, because the fault sits in the cloth. That condition, skew or bow, has its own inspection method and its own tolerance conversation with the mill, and it should be settled before the repeat data is accepted, not after the first failed lay. The sensible sequence runs: measure the repeat across the width, confirm the lines are square, agree the width-position rules for paired pieces, and only then release the marker. When the mill data, the arrival measurement and the marker plan all quote the same finished repeat, the same datum and the same match rank, the extra metreage the cutter asked for stops being extra at all. It becomes the exact, agreed price of a garment whose checks meet where they should.
