Twill tape is a flat twill-woven ribbon of cotton, linen, polyester, or wool. It may be used in sewing and tailoring to reinforce seams, make casings, bind edges, and make sturdy ties for closing garments (for example, on hospital gowns). Twill tape is also used in theatre to tie curtains, cable and scenery to various objects, or to tie cable coils so that they do not unroll.
A form of twill tape is sometimes used to wrap the handlebars of road bicycles.
