Case Study: Custom Curtain Lining Interlining Lining for a Shopify DTC Brand in Singapore
Curtain Lining Interlining Lining for a Shopify DTC Brand in Singapore
A Shopify DTC Brand approached us with a curtain lining interlining lining requirement for Singapore. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Suppliers who disappear once the deposit is paid
- Packaging that arrives crushed and unsellable
- Color drift between lab dips and bulk fabric

What we specified
| Product | Curtain Lining Interlining Lining |
|---|---|
| Client type | A Shopify DTC Brand |
| Market | Singapore |
| Order volume | 5,000 pieces across 3 colourways |
| Base fabric | French Linen |
| Decoration | Laser Engraving |
| Size range | XS-3XL |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around French Linen and locked shrinkage allowance before grading.
- Decoration was moved to Laser Engraving after strike-off tests showed better wash 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 size ratio specification.

Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Return rate linked to fit or workmanship stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
