Sewing Thread for a Startup Apparel Label in Ireland

A Startup Apparel Label approached us with a sewing thread requirement for the Ireland 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

  • Reorders that quietly changed supplier and changed the hand feel
  • MOQ that was quoted per colourway rather than per style
  • A trim that passed sampling but failed in-line because it was never cycle tested

MarketIreland
Order volume100,000 pieces across 3 specifications
Base materialWood
Standard size25 mm Width
FinishRainbow Iridescent Finish

How it was resolved

  1. We rebuilt the specification around Wood and locked the tolerance before bulk.
  2. The finish was moved to Chrome Plating after strike-off tests showed better durability.
  3. A pre-production sample was approved and retained as the golden reference.
  4. Production ran with in-line inspection and a mid-run photo report.
  5. Cartons were packed to the client's own barcode and ratio specification.

Result

  • 100,000 pieces delivered inside the 10-week window.
  • Unit cost held within 4.5% 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

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
