Just a short tutorial of the type of work I bring into the classroom. Visiting the K-5 level classes I try to encourage a quick sketch technique based on using simple shapes and line. I always start with a warm up session before we begin. In these examples I am using Manga Studio and a calligraphy pen tool for thick and think lines. In class I will use a broad tip marker, or a brush pen, on newsprint . For the under drawing I use a prismacolor blue pencil or any soft lead.
The hardest concept to convey seems to be the rough experimentation. I want the kids to fill the page with gestures, eyes or feather studies. Often this is the hardest part, as they like to darken lines, erase and get detailed a little to soon. I try to encourage small studies on a single page. Often I will draw lightly and messy, just to show how I am playing with options before picking what I like and going back to darken the lines. They really seem surprised to see me scribble over a drawing or draw an "x" over parts. Then they see how the under drawing really disappears as the marker comes out and the dark lines become dominant.
Have fun and keep sketching....
