At other times I may set limits such as lines and circles only, or create patterns using an object and its variations.
In this first one, I limited the kinds of shapes:
|Circles Squares Triangles (pigment ink, Sharpie pens)|
In the next one, leaf shapes:
|Leaves (pigment ink, Copic markers)|
I find drawing patterns allows the busy-ness in my brain to recede and I settle into a calmer place :-)
