It requires a delicate touch.
For the ripstop, the problem is all the loose threads kinda clog up the surface. You don't have to move fast, just be careful to keep the hot surface on the very edges. If you move too fast, you can make a mistake, and the iron will definitely create a gouge in an otherwise straight line.
For ropes, nothing to it. Just touch as necessary and use the iron like a paintbrush to shape the ends to your liking. You can even cut rope this way, "cauterizing the wound" as you go.
I've found that burning creates a hard bubble on the end. Not bad, but not smooth.
