My first duty station I got hold of a parachute and used it exclusively on every model I built. It sealed with dope fast, had ripstop stitching so you never had to worry about puncture or fraying,shrank beautifully, and it had white and orange pieces in it. It was really a great deal for me, after all I only got $38.50 every 2 weeks at the time. Of course it isn't too relevent as parachutes were nylon not silk.
