If you liked the red språng sash on the ROM website I pointed out the other day, have a look at Accession No: NGA 2009.187 on the National Gallery of Australia website. Similar in colour, pattern, and fibre type apart from the addition of metallic yarn. Different in geographical origin (Pakistan) and time period (nineteenth century).
It is described as a belt or drawstring and it is narrow, 9 centimetres by 206 cm (about 3.5 inches by 81 inches). By comparison the ROM's sash is 28 cm by 302 cm (about 11 inches by 119 inches).
