I used Katherine at http://pinacoladas.net/ to make my illustration seen here. She was amazing and very reasonably priced and fast. I gave her creative feedom with colors but told her my basic idea. I then designed the website around her illustration. I'd highly reccomend her. Otherwise if you have some basic programs like illustrator or flash (yes i use flash for drawing, lol) they are pretty easy to use. I did the illustration for Web Savvy Mama (My webdesign site) on my own. I had Katherine do the one for Baby Space because I didnt have time and wanted something totally different.
