Plaid Matching on a 30-Metre Roll
A workshop in Barpeta has 30 m of 112 cm-wide cotton fabric printed with a large plaid: the repeat measures 8 cm in both directions and the lines are not symmetrical. The order is for 24 identical kurtas for a folk-dance troupe, and the troupe leader insists that the horizontal lines must run continuously across front, back and sleeves when the kurta is worn. A trial marker shows that one kurta needs 1.15 m of fabric at 112 cm width when the pieces are laid with no attempt at plaid matching. The fabric also has a 40 cm shaded patch near one end and two small weaving defects. The workshop has one 3 m cutting table, shears, a wooden metre scale, tailor's chalk and pins; there is no computerised marker. Delivery is in 12 days and the troupe has already paid a 30% advance.
1. Calculate whether 30 m is enough for 24 kurtas. Show how the matching allowance and the fabric defects enter the calculation, and state what you would do about any shortfall.

Base requirement: 24 × 1.15 m = 27.6 m with no matching.
Matching allowance: with an 8 cm repeat running both ways, each garment set needs roughly one extra repeat to bring the front, back and sleeve lines into register, plus a little for the join at the side seams. A practical allowance is 10–12%: 27.6 × 1.12 ≈ 30.9 m.
Defect allowance: the 40 cm shaded end cannot be used for visible panels, and two weaving defects will force the marker to skip small areas. Budget about 0.6–0.8 m, taking the true requirement to about 31.5–31.7 m.
Conclusion: 30 m is short by roughly 2 m, and cutting anyway would mean either mismatched lines (rejection by the troupe leader, who has specified matching) or 22–23 kurtas instead of 24.
Action: buy 3 m more from the same dye lot immediately, before cutting, so the shade matches; if it is unavailable, reduce the order openly to 22 kurtas and refund the difference, or use the plaid only on body panels with plain matching fabric for sleeves if the troupe accepts a design change. Cutting first and discovering the shortage later would be the costly error - the advance is not a licence to gamble on fabric.
2. Describe the layout and marking precautions you would take when cutting this plaid, given that only hand tools are available.

- Keep all pieces on grain. Each pattern piece's grain line must be laid parallel to the selvedge; measure the distance from the grain line to the selvedge at both ends with the wooden scale. Off-grain plaid distorts and the lines will never match after stitching.
- Cut single ply, or at most two plies. Plaid matching across multiple plies is almost impossible with shears and no marker; single-ply cutting costs time but guarantees register. Allocate the extra days within the 12-day delivery window.
- Mark the match points before cutting. Draw a chalk line along one repeat on the fabric and transfer corresponding notches to each piece at the seam line, so the tailor has a reference at the machine, not just at the cutting table.
- Mirror the sleeves. Left and right sleeves must be cut as a mirrored pair from the same repeat band; otherwise one sleeve runs the opposite way.
- Avoid the shaded end and defects. Chalk-circle the defects and the 40 cm shaded patch and lay pattern pieces around them; keep the shaded area for facings, yokes or pocket bags.
- Allow properly. Add 1.5 cm seam allowance at side and shoulder seams (needed for matching adjustment) and 4 cm at the hem; pin sparingly inside the seam line so pin holes do not show, and chalk on the wrong side only.
- Label bundles. Number every cut kurta and keep its pieces pinned together - mixed bundles are the usual cause of mismatched fronts and backs.
