   You might want to overcast a bound edge with a serger if it's very lightweight. Practice your settings on scraps first because much of it will be on the bias and therefore unstable.
   If you prefer a more traditional turned hem, I suggest getting hold of a glue stick and carefully fixing the edge in place (including any little pleats) before you sew. Make sure tension isn't too tight and try to sew in one run all the way round.

   Oh, and if it's a bit more substantial fabric, I would put a running stitch around the edge first and gather it slightly to ease into place before basting.

   I usually Serge the Hem edge using a slight differential setting. It decreases the cicumference enough that a narrow Hem lies flat.
