Seam Tape for a Theatre Costume Workshop in Poland
A Theatre Costume Workshop approached us with a seam tape requirement for the Poland market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Shade drift between the approved lab dip and the bulk lot
- An interlining that bubbled after the first press
- Elastic that lost recovery after three washes
What we specified
| Item | Seam Tape |
|---|---|
| Client type | A Theatre Costume Workshop |
| Market | Poland |
| Order volume | 50,000 pieces across 6 specifications |
| Base material | Nickel Silver |
| Standard size | 20 mm Width |
| Finish | Mercerised Finish |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ISO 9001 |
How it was resolved
- We rebuilt the specification around Nickel Silver and locked the tolerance before bulk.
- The finish was moved to Rose Gold Plating after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
Result
- 50,000 pieces delivered inside the 5-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
