My art teacher would set up a still set in the middle of the room using old props, paint sheets, broken chairs, mugs, reeds and other odds 'n' ends. From that we would do 8-10 second sketches (see below).
Eventually we progressed onto shading, texture, patterns, etc. Below is one of my most prized drawings. I've never been able to do folds before and to do such was a great feeling, the most realistic technique I've ever used. It's not perfect; but I'm not complaining.
Hope you like it.
