Finding clip art to use for commercial projects, to decorate items to sell, or to use on a commercial Web page takes a bit of time and you will probably need to buy the clip art in order to obtain permission and a license to use it commercially. Browse several collections of links to Web sites with clip art packages that you might be able to use commercially.
Before purchasing any clip art individually or in a package, please ensure that the clip art may, indeed, be used commercially in the project you will use it for. If the license (terms of usage) is not clear to you, then email for more information before buying the clip art.

Using Search Engines:
You might also use search engines to locate topic specific clip art for commercial purposes. I used the Google Search Engine at http://www.google.com to find links to topic specific clip art. I put the following words and spaces in the search area, bird clip art use for commercial projects, and came up with multiple links to sites with bird clip art. Change the first word in the search line to whatever clip art you want to find, for instance, change bird to flower, bird to children, bird to baseball, or any other specific topic of clip art you want to locate.
Now that you have used a search engine to find a large list of clip art that may be used, supposedly, for commercial projects you will need to keep in mind several points about search engine lists, terms of usage, the word free, and Webmasters.
