Greetings everybody.

I recently recieved a request to shave the legs of a lady friend of mine.

I know this is common place, but this is not quite the norm.
This friend suffers from MS, and can no longer take care of this once simple task on her own. She loves the idea of my doing it with a st8, but she can not hold a sitting position for an extended length of time.
Does anybody have any words of wisdom for how this might best be handled with my lady friend laying on her back? (this is the position she is most comfortable with for long periods)
I can raise her legs somewhat, but I am concerned with the "blind shave" of underneath. Helpful hints anybody?
