What weave is used in Drapery Casement?

• A. plain weave
• B. satin weave
• C. leno weave
• D. twill weave

Answer: (C)

Leno weave creates an open, stable mesh by twisting adjacent warp yarns around the weft, locking them in place so the fabric stays square and resistant to shifting. This makes a drapery casement fabric airy and breathable while still holding its shape at the edges, which is ideal for curtains that need to hang cleanly without sagging or sagging gaps. Plain weave would be too tight and not give the open, airy effect; satin weave produces a smooth surface with long floats and lacks the structure to keep an open mesh stable; twill weave creates diagonal ridges and a different drape, not the open, stable mesh needed for casement areas.
