Two hands would definately make things easier- I just wish I could do it!
You'll have to contort yourself into a variety of seemingly impossible positions. but it will soon all (or most of it) come naturally. If you're right handed, a S-N pass on the left side of your face will be much easier than on the right side. Using the opposite hand helps the most for a N-S pass on the left side, or a S-N pass on the right side.
