While printed or dyed furnishing materials have an inherent resistance to fading, all fabrics will fade eventually. Therefore, we suggest lining your curtains if practical and drawing them back from the window during daylight whenever possible.
All woven fabrics, especially those made from natural fibres, will shrink to a certain extent and we recommend an allowance of 3% to 5% for this process. Even dry cleaning can cause shrinkage, although usually to a lesser degree than washing. For this reason, it is best to allow generous hems, loosely stitched to enable adjustments after the first washing or cleaning; side seams or attached linings should be hand slipped if possible to allow for the differential movement between face and lining fabrics.
Curtains made from natural fibres may also shrink, or indeed drop, due to fluctuations in atmospheric conditions (for example, variation of temperature or humidity such as excessive heat or dryness from radiators or excessive moisture from condensation).
