The other thing is to just start with the things you cant move, like the pins of the IC, and then start placing resistors, capacitors such that one end is defined by which IC pin it connects to, and the other end is defined by the length of the resistor/capacitor, etc. I have built hundreds of plug-board circuits, and I always just winged it, looking at the schematic, and checking things off as I placed them on the plug board. I never created a drawing of the layout, first....
