Today's lesson comes from John G Garratt ('Model Soldiers for the Connoisseur', Weidenfeld and Nicolson, 1972, p50):
'There is no logical reason, except possibly as a technical exercise of dubious merits, why eyes should be painted in detail at all.'
I'm with Garratt on this one, unless you want an army of Wilko Johnsons chopping out riffs across your wargames table then enough with the staring eyes - less is more, merely suggesting eyes is much more effective for 30mm and under i reckon.
That said, think what you could do with an army of Wilkos...
