I have high school students, and I start them out doing things that we did
the previous year on paper. Lines, ( straight and curved) texture
designs-etc. this way it shows them that what they can do on paper with a
pencil, can be done on the computer. It also gets them used to working
with a drawing pad or mouse. We only work in black, white and gray to
simulate drawing, and to cut out the interference of color.
