What is a twill weave? Which Indian fabrics use twill weave construction?

Twill is one of the three fundamental weave structures (along with plain weave and satin weave). In twill weave, each weft thread passes over one or more warp threads and then under two or more warp threads — creating a characteristic diagonal rib pattern on the fabric surface.

Why twill weave is important:

• Stronger than plain weave at the same thread count
• More drape than plain weave — falls more fluidly
• The diagonal structure creates visual texture without embellishment
• More resistant to wrinkles than plain weave
