The Continuous Line Owl

Can you create the owl below without ever letting your pencil leave the paper?

That is your challenge!  Try to draw the owl below using one continuous line, you may have to retrace lines.  Create textures and patterns throughout owl.  Let your lines be thin, and make your lines thick.  The more variety in your lines and patterns the better!  All you need is paper and a marker.

If you have the supplies, add color to your Owl.  In the examples blow  marker, watercolor and colored pencil were all used.
