Depending on where you live, this may be old hat for you, but I’ve lived 30 years on this earth and never seen a rope bannister before. And I just finished remodeling my staircase too. Besides being less expensive, easier to ship, easier to install, and way more interesting than a rigid handrail, a rope bannister is an awesome excuse to do some classic knotwork and play with giant-gauge rope. I’m pretty sure that’s a Matthew Walker knot (Wikipedia) there in the end of that one.
