and the hand doesn't sneak out afterwards and starts popping out and then it's useless, then the rest of all this stuff you just get it out of the way under the arm, it's all gone, right, this bit comes up between the two shoulder blades, don't make the mistake of bringing it across there, a lot of people do that, that won't do, you have to come round the back and between these two shoulder blades to get maximum support, you've got to hold this elbow up and then you tie it near the hand, now I recommend that you tie it and talk to your casualty, half tie it and say is that supporting you enough?
