Hi Mike,

> but does the 'star' or 'single skin' method look reasonably better at only three or four sides compared to six?

Well, it will tend to have only 3 or 4 lumps in it rather than 6 lumps in it... I'm not sure if that qualifies for "reasonably better" or not though.

It's fairly difficult to talk about such things in the abstract as the devil is in the details - certainly something that is almost planar already and very regularly shaped will be easier to fill in with any method. Do you have a particular three or four side hole that you would like to test with?
