I read a tip, via browsing on Amazon, from Carole Massey’s Drawing for the Absolute Beginner, in which she refers to Picasso having instructed young artists to draw a perfect circle.  And that it’s more effective to move your arm, in drawing the circle, from your elbow or shoulder rather than your wrist.   So, I was practicing those today.  My circles are still fairly elliptical, and I was drawing them way too fast, anyway.  I also tried drawing them with my left hand, and seemed to be more accurate with my left rather than my right hand.  

But I was also working somewhat quickly as a form of confidence – doubting my ability to create a circular line could potentially mess up my circle.
