I'd like to create an icon font for use in a web application. fontAwesome, Iconic, fontomas are examples of what I'd like to do but I need to use custom icons. I'm not sure where to start. Any help is appreciated.
Inkscape is a great free application for creating graphics with vectors (what modern fonts are made of).
FontForge is a great free application for creating fonts, and can import SVG (a great free vector graphics format) from Inkscape.
