Joining this material - adding tabling
Use 6 mm wide double sided tape, ref TS-06, to make seams to join the panels of small sails. Use 8 or 10 mm wide Mylar tape, ref TM-08 or TM-10, for the luff reinforcement of mainsails and headsails. And use 2 mm or 4 mm wide Mylar tape, ref TM-02 or TM-04, for leech tapes.
