Embossing stylus tools, Elderly Female Portrait
Step by Step

As promised here is a photo of the embossing and stylus tools I use to create the negative areas in this drawing. If you use these tools with the x-acto knife when doing hair for example, you can really create a rich depth that can be a long process to do with just pencils on there own, these tools combined will also speed up your drawing time.
If you have any questions please ask.
