Another thumbs up for cotton, twine and shellac. You can go multiple coats and get it as slick as Benotto, or just a few and keep it tacky. Shellac "glues" the tape together and makes it nearly indestrutable. I used to redo my tape every year, now it just gets cleaned and re-shellaced.
One thing I'd like to try is dying white twill with coffee (I've heard it's been done), and shellac with amber colored.
White with amber
Orange and amber (this one looks a bit like plastic, but "broke in" nicely)
