Ian, try asking her to move about in different ways, forward, back, side to side without losing the float in the rope. It's not easy at first as we have to be so aware of the rope that we're not going to pull the slack out of it. Getting the horse walking from standing might require a bit of ingenuity but once it starts coming together the feeling is awesome. To remove pressure I unhalter the horse and walk away for half a minute and admire the scenery and not think of the horse. The halter forces the horse to have a connection, I want him to want one.
