Materials for your sketchbook

Sketchbooks are wonderful to use to create, capture, or express ideas and feelings. One of the most traditional materials you can use is a pencil. However, in this video I will show you other materials you can use with your sketchbook. If you have used any of the above or other materials that I did not mention, comment them below. I'm curious to see what other artists and creatives use for their sketchbook.
