Abstract
A method of producing a stitched perforated sheet material including providing a sheet material (3) with a perforated region 4 and an unperforated region (5). The sheet material is then stitched in the unperforated region, but adjacent to the perforated region. This gives an overall perforated appearance whilst avoiding the problems associated with stitching through a perforated material.
