Line is in wrong.
Start by put ONE of string ends in from the FRONT to BACK one of the end holes, put this same end from BACK to FRONT of other outside hole.
You now have two ends comming out the front of the two outside holes.
Take ends and Loop over top to the BACK of the middle hole, put both ends through the middle hole from the BACK to the FRONT
You end up with 2 strings coming out of middle hole.
