Mark and Line
Mark making is a critical component of art, especially in terms of 2 dimensional pieces such as drawing and painting. There are many different kinds of art media out there, and each one provides its own distinctive markings. For simplicity's sake, I created the drawing above entirely with ink. Three black pens were used, one ball point for the 'trees', one small felt pen for the thin lines around the trees creating the 'sky' and a third marker-esque for the water/muddy ground. Using the different pens and their distinctive markings allowed me to create the three separate elements, while the different markings using the same pen in the trees creates the difference between the imaginary leaves and the wooden trunk and branches.
Grids can be used in a variety of ways, from its use as an aid in perspective or in replicating something to being the base or incorporated as a creative part of a piece in a more raw form.
