My Drawing has been sacked

Today, we dropped everything and drew. What we drew though, was the interesting part of the class. Our teacher, set up sacks full of crazy and random objects. Ranging from water, to ink, and to a box. Our goals, were to start drawing the big general things at first and then incorporate the smaller things. The way i accomplished this was to take my mind off of the things inside the sacks and just draw the outlines. After I had completed that i moved on to the objects inside and drawing their outlines. Then i started to draw the little things that i could see, like crinkles and ruffles in the plastic. This class was very interesting because i saw how much i have improved at drawing since the first class.
