Black, white and red all over is the challenge that the Diva issued this week. When I sat down to do this last night I really had no idea of what I wanted to to do so I really just let it flow. I started with a continuous line string. (See below). In this type of string you can alternate colors or patterns easily - just like a checkerboard. It simply requires that you pay attention and go from one section to the next and not skip around. Striping is the tangle pattern that came to mind first so I went with it. I alternated red penwork and black penwork. Shading was either a pencil on the black sections or red colored pencils on the red sections. At the end I felt I had a lot of red so I colored the background in with black.

A continuous line string is where you put the pencil down and start drawing and don't pick it up until you reconnect it to your starting point. Here it is entirely self-contained within the tile. I used the one on the left for the tile above. I decided not to use the one on the right because there were too many small sections to work with. I've also done continuous line strings that go off the tile. I'll have to do a demo on that later.
