A sail was made from draughting film, with panels joined using standard double sided tape. The panels allow a little shape to be added to the sail, by gently pulling the seam at the luff. The three corners were reinforced with extra layers of film stuck on with spray mount. The luff was reinforced with magic tape to form a bolt rope. Dressmakers eyelets were added to attach the sail to the mast. I found some grommets which were threaded on to the boom to allow the various lines to be adjusted.
