Captweaver,
If you need ropes of certain colors, try checking your local outdoor sports stores. Rock-Climbing rope is available in all sorts of "Hurt your eyes" combinations, as well as "boring" colors, too.
(it's also rated for about a 2000 pound tensile strength :) )
thanx capn C,
have tried some of that stuff,but they usually have it in some nasty synthetic fiber and those cut in when used on the body.
I like a good soft cotton.
:)
