I do almost all of my sketching on paper, starting with pencil to get the shapes right and then moving on to shading with studio markers and finally defining edges with black marker and fineliner. When communicating ideas and brainstorming, I like to do rapid sketches directly with markers and add a hint of colour to help bring them to life. Below are some examples of presentation sketches I have created for various projects.

Mindmaps are the tool I use most frequently for brainstorming, along with sticky notes when I want to categorise and reorganise ideas. Some examples of previous brainstorming work are shown here.
