A fibrous assembly comprises two components, the first component providing a visual indication of when a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended. The first and second components are movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the pre-determined tensile load is applied to the assembly or when the fibres have been over-extended. The first component comprises auxetic yarn.
