Loved this technique and project! I didn't understand at first so i ended up drawing some lines around my crab sketch.  When i got to the legs i realized I was just supposed to stipple and not to any lines for the edges.  I love how the legs turned out the most without the lines.  I am working on a seahorse next, the sketch came out good i hope i can make the stippling really show the unique bone structure of the seahorse. 

Thanks for putting together this class I really liked the length of the class and the demo.
