A & B

img_0201Here are good examples of different lines that I can get.  (Of course there are tons more)  The pot on the left was drawn on when bone dry with a sharp needle tool.  The cup on the right was drawn on with my loop tool at the leather hard state.  Combining these two tools plus using other techniques such as stippling or cross hatching would yield a varied and interesting drawing (if you're after that sort of thing)
