I quote:
Stopping Runs / Pulls in Sweaters
(super-glue) is a great accessory to stash in case your nylon garments run or your sweater catches. By dabbing a bit of super-glue on the start of the run or pull, the super-glue seals the nylon fibres and they no longer continue to run... The same is true for a frayed or unraveling edge on a sweater. By dabbing a bit of super-glue on the fibres, they will be held in place, preventing further damage.
This advice comes with the usual health warnings - don't blame me if it all goes belly-up... or else you stick you fingers together, or worse, your fingers to your Paramo!
Just don't try this with anything made of cotton....
