This year I brought along my water refillable brush and a sketch and wash pencil by "General" , some manilla paper and some loose strathmore paper out of an old sketch book. I was set.
The trick to making action drawings is in your skill to observe and record with your eye and subconscious mind. Watching consistently makes you see the rhythm of movement being created by the model. In my case, jumping rope. It doesn't matter if the model you are observing moves away while you are drawing. The next jumper who comes across your line of vision may be doing the same movements. Your eyes must linger on the contour of the figure ( model) being observed, every fraction of movement being followed by your pupil is like drawing with your eyes. Don't think about the pencil in your hand. The hand moves automatically with the eyes, following the contour and gesture. Very quick, scratches, dashes, dots and squiggles. Now move on to the next drawing. Each drawing taking only seconds to draw. A most exhilarating feeling! Try it, as an art educator, you have no shortage of models, for the rest of you, go visit the local playground, watch a sport on TV, go to the zoo.
