Metres of fabric and lining for made-to-measure curtains.
How this works
Total fabric width = (rail width + 15 cm for overlap and returns) x the heading fullness: 2.5 for pencil pleat, 2.2 for pinch pleat and wave, 1.8 for eyelet, 1.5 for tab top. Divide by the usable fabric width to get the number of widths. Each cut drop adds 25 cm for hems and heading (30 cm for eyelets), rounded up to the pattern repeat.
