Especially when it is Natural Hemp Rope, available from Mr S:
Although it doesn’t have the artificial smoothness of a plastic or acrylic rope, it’s soft (and gets softer the more you use it) and it is great-looking against the skin. This Natural Hemp Rope comes from Europe and is available in three sizes: 6mm (small), 5/16″ (medium), or a 1/2″ (thicker) diameter.

A pretty knowledgeable friend of mine told me the following:
‘Hemp rope is made from marijuana stalks. It was Dupont who got marijuana declared to be an illegal substance years ago in order to eliminate the competition to its nylon rope.’
Hemp makes the best rope.
