Try doing figure 8s. Sounds easy but try and get them a nice symmetrical shape every time, with the crossing point right in front of you and in the middle of the 8. With loops try and get to the point where the loop starts at the same point every time and is the same shape. All up try and get to the point where you can put the plane consistently at any point on your circuit.
Nice thing is you can do this with any plane.
