looks very nice my vines are of a similar build but i used different colored grout instead of kitty litter.

my 2c on the matter is that if you can find a dark brown nylon twine or rope you are way ahead of the curve. on the ones i made any spot where the coating rubbed off shows off the white nylon. one rope i used was brown poly and it is much less of a problem with that one.
