The difficult part about this one is that people all have odd shaped heads, now and you find that if you put them on too high they squidge off like that, and you've got to think of bandaging an egg basically, if you had an egg with a little hole in one end and you've got to put a bandage round you'd have to put it very carefully round the widest bit wouldn't you for it to stay firm and that's the secret, everyone's heads different and as you put it round you've got to see where you can get it, where, sometimes it's over the ears, sometimes it's above the ears according to the peoples' shaped, different shaped heads everyone's different, anything else?
