Worked example
With Curtain track/rod width = 200, Finished drop = 150, Fabric width = 137, Fullness = 2, Hem allowance = 30, Pattern repeat = 0:
CURTAIN FABRIC REQUIRED5.4 metres
- Fabric widths: 3 (1.5 per curtain on a pair)
- Cut drop per width: 180 cm
- Fullness used: 2x
- Hem allowance: 30 cm
- Pattern repeat: None (plain fabric)
Standard maker’s method: widths = track × fullness ÷ fabric width (round up); total = widths × cut drop. Fullness guide: 1.5x light gather, 2x standard, 2.5x heavy/sheers. Always round up, never down.
