The technique of sewing curtains, curtain waves, needle lines, and stitches greatly determines the longevity and aesthetics of a set of curtains.
The standard dipping rate for fabric curtains should be at least 1m of wall = 2.7 – 3.0m of fabric. If lower than this standard, curtain waves are often sparse, reducing light blocking, reducing aesthetics.
The dipping standard rate of chiffon curtain can be from 2.5 – 2.7m and depends on the chiffon material.
