It's also important to get the tripod knot correct and lay the poles in the right sequence, once the tripod poles are in the right position they must not be moved, the skin support poles can be moved inwards or outwards to get the right height and tension, I was going to post a pic of one of our frames which shows the correct settings, but it seems a bit complicated and I'm a technophobe.
