This can be a bit like dominoes. It can take both a great deal of thought and time to set it up properly. But the effort is worth it. It is not an expensive thing to do. Any number of pegs you require from 10 to 1000 or more if you wish and a length of thin nylon parachute cord.
Some people drill a hole big enough to accommodate the cord in one arm of the peg.
I prefer to thread the cord through the last hole or through the center of the spring to give me an even leverage. I tie a small knot, either side of the peg, to keep the cord in place. The patterns one can have are endless and only limited by the your own imagination. A spiral around the body from breasts down to calves is wonderful and has the added effect of a submissive in spinning top mode. The pegs can be placed as close as you wish to each other.
