Ran across a new artist, at least new for me - Kathryn Lee Smith. She creates wonderful white line prints, and also seems to break the rules (as if there ever were any rules).
For example, her print, "Three Poppies", breaks away from the rectangular print style most often seen in these sort of prints, to create a more engaging image. She also plays with the colors in her prints to create various types of shading effects.
I strongly encourage your visiting her website. (http://www.kathrynleesmithwhitelineprints.com/)
