My wife used to climb, but no more! So she let me cut up her old climbing rope to make stuff with.
Here's a climbing rope based clothes hanger, made by tying two vertical rope at slight angles on either side of the porch, and then running clothesline between them. It makes for 3 tiers of stadium style clothesline. And the knots can be pushed up, when done drying, or brought down (it's a sliding knot that holds tension when there's weight on the line.
