Drawing with an eraser!
The link should take you to a tutorial on how to draw an outer space picture in reverse!! You can do this by rubbing out a charcoal background with an eraser.
1. Begin by shading a piece of white paper all over using a normal lead pencil or charcoal if you have some to form a dark background.
2. You can choose any picture of your choice to be drawn in the dark background using an eraser.
This has the reverse effect of drawing with a pencil as the image is created by erasing the background instead of adding to it. You could use different sized rubbers for different effects.
Have fun experimenting!! Share your art on the blog.
