When I started Pro Theme Design I was thinking about what I wanted it to be and, whilst I wanted to sell Premium Themes, I also wanted to expand my knowledge, and the first way I am going to do this is by designing, and giving away for free, a free icon set.
Well this is it, Circular. In creating the set I learnt an awful lot about icon design, both technically and creatively - and will talk more about this on my personal website. Some of the icons I’m really proud of, and others could do with some work. I can promise you I don’t (often) make the same mistake twice, so my second set will be immeasurably better 
As you can see I use some of the icons on this site, and hopefully someone out there will be able to make use of them in some way.
You can get more details and the download on the Circular icons page.
