I was wondering if it would be different seeing as there are two layers (unlike normal cordage)
(yes, I `do` know how to heatseal cord, honest!)
another method I have seen done on boats is to use a bit of heatshrink tubing. (something which has a thousand uses)
Looking though what I have got I seem to have 7 lengths of about 15-20 foot each, now is the time to learn some cordage projects!
