A flat braid made by plaiting dried grasses or other vegetable fibres, most commonly used in millinery. Sennits are very strong and used in a variety of ways. When coiled, its depth is useful for creating flat structures such as place mats, floor mats and bedding mats. It can alternatively be formed into slightly overlapping spirals to make vertical and flat planes, for example the brim and the crown of a straw hat, as with boaters. It’s used in macramé, and in the southwest pacific for building boats and homes.
