How do you do a lettuce edge?

I hope to use a transparent fabric (silk Georgette), but also wanted to know in general how this finish. I have a serger with a rolled hem if that helps .. I'm sure I've seen them finish this way.

Adjust the differential to "stretch", and start biting on pieces - try it on the same grainlines the edges that you propose to lettuce.
