One of the best pieces of drawing advice I heard was in my Industrial Drawing class at Pratt Institute - "Draw bigger." The industrial drawing class trained our whole arm muscles, not just our wrists. One of my classmates was struggling to draw perspective detail. Not only was she limiting her physical ability to draw, she was limiting her ability to think. The small space was crowded with previous attempts and she quite literally drew herself into a box.
It was also the first time in years that I sketched on large, 18x24 paper. I realized why I never got into sketching in little sketchbooks - my arm and vision was limited. Drawing on newsprint is even more liberating - it's the cheapest paper available, and therefore you don't feel guilty about "wasting" it. There's no pressure of drawing something that will have to remain in a bounded notebook. Prismacolor colored pencils glide on newsprint smoothly
I developed the direction of this illustration by sketching various letters and organic shapes on newsprint. In case of the letter D, I was "doodling" randomly, but with purpose. I saw the letter D take shape and I ran with it.
The letter T is the first letter I worked on. I started with some loose sketching on bristol paper with a "dripping" shape in mind. I avoided placing any dark lines or shading since I was still working out the shape. It's helpful to place the drawing across the room to view if the proportions are working. I realized I should elongate the stem before I started to shade.
This is one of my favorite designs - the same drawing represents the letter "E" and "A" when I rotate it.
