This is one of three [maybe more if I feel it is a constructive enough excercise] step by step breakdowns of drawing hands. I had some notes I wrote to accompany this, but I cant find them. So hopefully it will all come back to me.
Anyway, I will be doing a series of hands holding objects. As that can be a double tricky, if you refer to my theory of using the vertical lines to help you construct the entire drawing it will lessen the stress for you.
