I've added a new sketches page to the 'portfolio' section of my website. It doesn't matter what you're designing, usually the first stages of any project are the initial sketches. It matters not whether they are doodles or scribbles or even how good they are, it's always good to let your brain run free and let the ideas flow.
Personally I start all my projects with a good old fashion pencil and paper. I love the freedom and feel of a sharp 2B on some crisp white sheets! You'll find some random examples of my sketches and early stages of designs. Many ideas never actually make it to a final piece of finished artwork so it's a shame to keep them hidden away.
Here they are in all their glory, rough around the edges but also containing that all important 'spark' of an idea. Enjoy!
