A washer ( 100 ) comprising wadding material and having an aperture ( 104 ) extending therethrough is disclosed. The wadding material is compressed at least around the periphery ( 102 ) of the aperture ( 104 ). The compressed wadding material is sufficiently elastic such that, when fitted to upholstery together with a tuft, the dimensions of the aperture may increase sufficiently to accommodate a tufting needle and then return to its original dimensions after withdrawal of the needle so as to, prevent disengagement of the tuft.
