Quote - weird.  i don't have them smooth out at all.  my problem with my hems is purely me.  i haven't found a good way to make their basic shape. 

Model them as just part of the flat mesh, select the ring ot polys around the edge, now depending on your modeller, extrude/bevel/fillet those polys, then softent the edges so they are not razor sharp.

Hope that makes sense.
