You should check out the lf (lacefront) section on BHM (Black Hair Media). I have one, but haven't officially applied it yet since I am torn with what to do with my hair underneath. Usually, women will braid the hair in cornrows, and some will even be brave enough to be bald (on purpose!) underneath. Believe it or not, but being bald underneath makes the lf look even more natural and believable.
Anywho, I believe BHM has the BEST info on vendor and application techniques.
