Yesterday, I did some experimenting with hardness of drawing pencils. I printed out a guide of the different hardness of pencils and what they looked like. I have decided the 4B is the best for my value sketches and erases the best for my Watercolor sketches. I was having trouble erasing the sketch on watercolor paper and I discovered that my pencil was too hard and I was holding it wrong. This little (5X7) sketch is a practice in using the painting knife for the grasses. I had fun with it. Today I go to the dentist..No Fun.
