Sanding green turned objects- what are the options?

So I had a lovely time green turning some bowls. I love them going oval as they dry. So now they are dry and no longer round what do i do to finish them? Hand sanding? :C Jim Carrol has these scotchbrite radial bristle discs (http://www.cws.au.com/shop/category/-scotchbrite-radial-bristle-discs). Anyone used them? What do other people do?
