The seam is particularly adapted for use with multi-filament yarns which comprise multi-ply fabrics. A novel method for producing this seam is disclosed which- comprises the insertion of a seaming coil, the removal of picks in adjacent fabric areas, the folding and sewing of such areas, the creation of a warp fringe, the weaving back of portions of that fringe into the fabric body, and the application of various fasteners including adhesive and sewing to create a unique, reliable seam providing substantially uniform thickness and air permeability across the full fabric width. A durable, reliable, non marking seam is accordingly provided.
