A rope walk is a place where rope is made. A typical rope has three strands. First each strand must be twisted while under tension which shortens it, but greatly increases its strength. Then three strands are twisted together until whole rope is twisted under tension. It has to be kept under tension for an expended period, so that the twist does not come out when the tension is released.
As a way of making a rope for ornamental use, a hobbyist can take three strands of strong string, each of a different color, if desired, and hitch one end to a strong hook, and then hitch each strand to each of three hooks mounted on a disk 120 degrees apart, with the hooks free to rotate. Then a spindle at center of the disk mounted so tightly so it cannot rotate is placed in the chuck of a hand twist drill, and with the whole length under moderate tension, the twist drill is rotated until the whole is rather tightly twisted. The tension has to be maintained perhaps twenty four hours, so that rope does not untwist when the tension is removed. Perhaps this gives an idea of what is done on a rope walk.

A rope walk is a place where rope is made?

That's rather interesting. By extension, I suppose I work in a writing walk, and you, wwh, worked in a health walk.

I do not understand, however, why it is that the rope, even after twenty-four hours, holds its shape. Is it wet when first twisted?
