Sorry, I think I was a bit unclear there: I use PVA glue to sightly stiffen the string (just put some on your thumb, run string between thumb and index finger, , wipe off excess, hang string over the desk lamp or something so the PVA can dry a little). Superglue I use for the actual gluing to the masts and so on (applied with a toothpick or what ever pointy implement is at hand).
