Recently, out of necessity, I happened upon a lovely variation of this tangle. I had made the rolling zigzag too wide and the filler loop didn't fill, so I added another. You can see it in both the tiles I did for Zentangle's Zenth (10th!) anniversary here. I really liked the effect and wanted to explore it more. Black Pearlz seemed to work nicely in some of the larger areas.

The string on both these tiles is something called a "blind string" or "shut-eye string" - simply do the string with your eyes closed! It often yields some nice wobbly lines and really interesting shapes. Try it sometime!
