Easy technic provided that you are good at drawing.
It's just about practicing the other way. Put a cylinder or a steel glass(yes, it's fine, I tried with it) on a paper. Start with writing, not the drawing. Don't look at paper, look at glass and try to write. When you are comfortable with it, try with some easy drawing. That's where I stopped. You can try further with complex art.
Don't blame me for bad hand writings after practicing this.
