Please bear with me if this question has been dealt with in a previous post,not sure how to word heading in "search" to find out,so I will ask directly.
Where does the L/arm actually "rotate" from?,in my attempts to maintain FLW(R/hander),I have found myself rotating my L/forearm,but get the feeling that it is not correct,should my L/arm be rotating from the shoulder and not the elbow?,both can be done ,butthe resultant finishes are quite different...What is right?....Thanks in advance

Where in the book is this covered...thanks
