Blind contour drawing allowed me to concentrate and focus on the lines I was seeing instead of the familiar shape of an object. For example, I know how the shape of a hand should look like but in this exercise I was able to see the different folds and curves just within one finger. I think this exercise adds on to the idea of fighting or ignoring what you know in your head and actually drawing what you see even if that goes against your pre-existing knowledge of the object.
