Core-spun weft yarns can give denim stretch; see [elastane](/materials/spandex-elastane) for stretch specifications. - **Weight and condition**: State oz/yd² or g/m² and whether the weight is before or after washing. Use ASTM D3776 for fabric mass per unit area.[\[1\]](https://store.astm.org/d3776_d3776m-20r25.html "Source 1: store.astm.org: /d3776_d3776m-20r25.html") - **Construction**: Give the yarn counts and the selected quality’s warp ends and weft picks per inch. ASTM D3775 covers end and pick counts.[\[2\]](https://store.astm.org/d3775-17r23.html "Source 2: store.astm.org: /d3775-17r23.html") - **Weave**: Specify the weave and twill direction. - **Usable width**: Give the usable width and its tolerance. - **Selvedge**: State whether [selvedge denim](/glossary#selvedge) is required. - **Fabric finish**: Specify the fabric finish and permitted shrinkage. - **Intended garment wash**: Identify the finished wash reference. - **Post-wash targets**: Set the shade, hand and garment measurements to approve.

Twill names a weave; denim is one of the fabrics made with it. Chino and gabardine also use twill; see [cotton twill](/materials/twill) for those cloths. ### Is denim the same as cotton? No. [Cotton](/materials/cotton) is a fibre; denim is a fabric. Denim can combine cotton with polyester. ### How does chambray differ from denim? Chambray uses a plain weave; classic denim uses 3/1 twill. [Compare chambray with denim](/materials/chambray) to see the two constructions. ### Can we buy denim fabric without ordering garments? Yes. We sell denim fabric on its own, by the metre, to garment makers. For a fabric-only quotation, send the fabric reference, specified weight and metreage. ### How long does a denim sample take? A first denim garment sample takes 4 to 10 days from an agreed brief. A question this does not answer?
