Cotton does seem nice, though it is a little too stretchy for my tastes. I would recommend true hemp. I heard of an online store called rawganique or something to that effect. Currently I am working on some cheap manilla hemp that I think may find it's way into the trash or soley used for non-bondage work. I do recommend the Doc Johnson's Bondage rope from a sex shop, it is cotton, Vixey says that it is comfortable and not that stretchy.
