Let’s talk about how to avoid smudging on your drawing.
If I were to tell you about the many times that I smudged my drawings before this trick, the number would at least be in the double digits.
If I had to describe smudging … It’s when the edge of your palm is resting on your drawing canvas, and it slipped your mind that your hand is in “the danger zone” with graphite. This is probably because you’re so focused on the progress of the drawing.
Later on you find out that your creation was almost ruined by this common culprit; You’ll notice the graphite on the edge of your palm as evidence of this horrendous crime scene.
To avoid accidents, like smudging, I typically use a 4 inch by 4 inch piece of printing paper, because it’s an even square. Printing paper usually has a smooth surface as well.
On a side note: If you have a larger hand, I would use a larger piece of paper.
You’ll then place that piece of paper in between the edge of your palm and your drawing canvas; You can avoid smudging pencil lines or areas already shaded this way while you draw.
