How this is worked out
  • Returns 3.5" each side; 3.5" centre overlap for a pair.
  • Side hems: 6" per panel. Bottom hem: 8" (double 4").
  • Heading allowance: Pinch pleat 8", Inverted pleat 8", Ripplefold 4", Rod pocket 6".
  • Widths round up, and to an even number for a pair so each panel matches.
  • Patterned fabric: each cut rounds up to whole repeats, plus one repeat for placement.
  • Lining: 54" wide, cut 4" shorter than the face fabric.
