Describe the basic weaves with neat diagrams and examples.

1. 1 · Open in two lines. A weave is the pattern in which warp and weft interlace. The three basic weaves are plain, twill and satin.
2. 2 · Draw the drafts. [Squared-paper drafts: plain chequerboard; 2/2 twill staircase; 5-harness satin with scattered marks]
3. 3 · Plain weave and variations.
   • Over one, under one; two harnesses; firm, reversible.
   • Rib (poplin) and basket (oxford).
4. 4 · Twill weave and variations.
   • Floats over two or more, shifting one step; diagonal wales; three harnesses.
   • Even, warp-faced (denim, drill), herringbone, pointed, steep.
5. 5 · Satin and sateen.
   • Satin: warp floats over 4+, scattered; five harnesses; lustrous, snags.
   • Sateen: weft floats; cotton; softer lustre.
6. 6 · Compare. Interlacing, harnesses, surface, durability, wrinkling and examples in a table.
7. 7 · Daily-life link. Drill or twill for chef coats and kitchen trousers; plain cotton for aprons; satin only for decorative linen.
8. 8 · Close in one line. Each basic weave gives a different balance of strength, lustre and comfort, which guides its end use.

Scoring tip: Drafts on squared paper are essential; one neat comparison table then finishes the answer quickly.
