Here are some simple icon designs. I like how easy clean they are and each one has a specific opening to it that allows the icon to be a part of the background. I also like how they are all see through and tie in well the background also.
I thought this design would be perfect since we were talking about symbols in class the other day! The audience are people who would like to buy the set of icons to use for commercial use. I love how the are all simple, black and white pictures. For the most part, a user can tell which kind of icon it is, and what it does!
