Shattuck, a Zentangle®-original pattern, can be drawn with straight lines or curved line ( Step-outs for the curved version)
To draw this tangleation, start where the pattern makes an inverted V and draw a slim triangle using one line of the original tangle as one side of the triangle.
OR….draw the slim triangle going in the opposite direction, again using the original line of the tangle as one side of the triangle.
That’ all there is to it!
