Domestic black rope wrap is available for about 12 cents a foot. One can also use mule tape for about 2 cents a foot.... Amazon. The mule tape is good for lesser diameters. The rope is prettier.
Word has it they won't let you into heaven if you have that cheap plastic clanging crap sleeves on your oars....so..... don't risk the afterlife
