Okay, so there you are you see, you're, you're a first aider and you come up to the person and you hold it the way you did last time and you think ah, now that's the wrong way round of course, there's my elbow point, there's my injured elbow, so I have to be that way round, mm, so you turn it round the other way, right, your elbow shape goes to the injured elbow and your long line goes straight up and down the line of the body, you arrange it so that you only just covering the forearm there, with just enough above the hand to tie your reef knot  that would be too little and that would be too much  just enough above the hands to tie your reef knot, the first thing you do is to tuck nice, big bit of material right under the hand and anchor it into position, just keep that resting there and all the rest of this goes under the arm up between the shoulder blades there and you tie your first half of the reef knot just above the fingers in the hollow of the neck here, now that's important because round the back here if you press on that bit of muscle there, there's a big band of muscle, if you've got a knot on that it gives a great deal of discomfort very quickly so you want to get the knots round in the hollow here that doesn't hurt your casualty, there, draw it up half the knot, is that tight enough?
