I was actually considering posting a tutorial exactly on this topic earlier this week, so apparently there is interest. I'll have to think more about it.

I'm quite interested indeed - I can't get the thicknesses of the outlines to match properly at all, and if I use Photoshop's contract-selection tool, I get too many rounded edges where there should be sharp edges, and I'm too lazy to go fix them all myself. I suppose I'll have to end up doing that eventually, though ...
