Most of the design professionals are expensive guys, especially when you are just starting off a project and have to wait for months for a cheque. But luckily there are a few folks dishing out freebies and of High Quality, that you can wait till your project is in good shape to get your own custom icons. Here is a grand list of freely usable icons. Many of them can be used for commercial projects, do remember to check their license terms.
- Many of the icon sets on smashing magazine are free for commercial use, check them out.
- The guys at UserInterfaceIcons are giving away some fantastic icons for free, grab them while they are around
- Another beautiful set over at DryIcons
- Another comprehensive collection from Smashing Magazine, this time with more icons for bloggers and web designers
- Very artsy sets over at noupe, If you are looking for social media icons you will find lots of them over here.
- If you are all set to shell out cash, I wouldn't hesitate to recommend the IconKit bundle, an excellent value for money package.
I think that's the best collection I could find on the web, and enough to get you started and last quite a while.
