Most buyers treat yarn booking as a back-office step. It is actually the moment your bulk timeline, cost and colour are locked. Get it wrong and the whole order shifts. Here are the four things every buyer should know before yarn is booked.
Why yarn booking decides your project
Yarn arrives 2-6 weeks after booking. That window sits inside your overall lead time — it cannot be skipped. Once a custom colour is dyed, it cannot be returned. Once the dye lot is paid for, the order direction is fixed. Three of your biggest cost levers (yarn type, colour count, MOQ per colour) all close the moment yarn is booked.
The 3 lead-time rules
| Yarn type | Standard lead time | Peak season (Jul-Sep) |
|---|---|---|
| Stock yarn (undyed, in mill stock) | 3-5 days | 1-2 weeks |
| Standard fibre, dyed to colour | 2-3 weeks | 4-5 weeks |
| Specialty fibre (cashmere, merino blend) | 4-6 weeks | 8-10 weeks |
Book early enough that yarn arrives before your knitting machine slot opens. Late yarn = pushed bulk = missed launch.
The dye lot minimum trap
Most mills require 30-100 kg per dyed colour. A 50-pc bulk in 4 colours often falls below the minimum on every colour — and the mill charges a 10-25% small-lot surcharge per colour. Two practical fixes:
- Cut colours. 4 colours → 2 colours often eliminates surcharges and saves 8-15% on yarn.
- Combine programs. If you have multiple styles in the same yarn, book one larger lot for all of them.
Pre-booking checklist
- Yarn fibre and blend ratio confirmed.
- Yarn count (e.g. 2/26, 2/28) confirmed.
- Pantone colour code or physical reference signed off.
- Quantity per colour calculated (avoid sub-minimum surcharges).
- Mill name and lot number recorded for traceability.
- Cancellation and surcharge terms in writing.
