My tangle pattern "Pindo"

Here's another pattern based on the trunk of a palm tree. *shakes head*  There is just no beating Mother Nature when it comes to creating designs.  All we can do is study and learn. 

Pindo could probably be considered a tangleation, though I'm not sure of exactly what pattern.  Because, like many patterns it is based on repeating rows of a shape.  In this case, the shape is a triangular wedge.  A row of large wedges is laid down, and the smaller wedges are repeated in a triangular pattern. 

Variations could be created by varying the shape.  Imagine this done with ovals or rectangles.  I didn't add this image in with the steps because it becomes difficult to keep the large wedge shapes even, but keep it in mind when you are working step 3.
