Thanks! I can barely get a handful of jumps in a row without messing up my timing, but this will be good reason to practice more.

This rope cost quite a bit since I bought it from a retail craft store ($42 if I recall), but I suspect if I bought rope in bulk I could cut that price in half. It's definitely possible to do this for less (especially if using plastic-based ropes), but there's something special about the natural feeling of leather and the patina as it ages.

Once I had the rope, I just learned the heaving line knot, and it took a handful of attempts to get the handle just the way I wanted it.
