GRA - 3rd class drawing

Still working with the sculpture teacher. We had to bring an object from home. In class we are drawing it in different ways; right, left hand, eyes closed, different materials, etc. This is fun to do, even if it seems to lead nowhere. Then we're supposed to incorporate parts of the academy into the drawing of the object by 'rubbing.' I have no idea what to aim for, so I wander around not finding my thing at all. Teacher is very busy with other people, I get no feed back and get totally stuck. No pictures today. My drawings are garbage.
