For our first real project in my Digital Illustration class, we were to choose a subject and create a circular emblem of sorts for it in black and white using Illustrator. Examples for subjects included things like sports, dance, hobbies, people, etc. etc. I chose to do mine on dairy products. :B
This was pretty much my first serious attempt at doing stuff in Illustrator outside of the Slime Mansion logo I did before, so a lot of time was spent fudging around, but basically I became very familiar with the Blend Tool while working with this project @_@ Although I haven't really used it again; it's good for black-and-white stuff, but the next project we did was in color, so I became best friends with a different tool for that one, which I'll post here eeeveentuaallyyyy!
