Grab a spoil of rope and git the length of rope at least twice your arm length.
DO NOT CUT THE ROPE YET.
Grab the end of the rope your first started out with and begin ting it to the bolt, about 3 raps is enough. and then BURN the other end of the rope. cutting rope will leave the ends split and can undo the entire rope. burning cuts and binds them together.
