Frequently Asked Questions

  • Uneven floor? Use shortest drop measurement across three points.
  • Bay window? Measure full track length; add 10% for curves.
  • Too narrow pole? Select next size up for proper gather.
  • Eyelet vs pencil? Eyelet for poles up to 35mm; pencil for tracks.
  • Fullness factor? 2x suits most; 2.5x for heavier fabrics.
  • Shorten curtains? Possible on all ready-made; allow 3-5cm extra.

Common Mistakes to Avoid

  • Measuring window instead of pole/track width.
  • Ignoring pole extension (needs 15cm each side).
  • Not checking floor level in multiple spots.
  • Forgetting heading type affects starting point.
  • Choosing insufficient fullness (under 1.5x looks flat).
