Woven fabric consists of a warp (up and down the loom) filled with a weft (side to side).The strands of yarn that make up the warp are called ends, the weft is composed of picks.

Endless Stripe Calico is a variation on the calico used for shirts, and for jeans back pocket linings, since Tender’s first production. For this version, however, ends of warp yarn are pulled out during weaving, causing a small gap in the fabric that forms a vertical stripe. When the garments are washed or dyed the gap draws in, creating a slight ridge and an unusual variation in texture and colour.
