I've just made available a set of 35 stock web icons for sale (through PayPal), dubbed Stockholm™ (stock icons, Cederholm... yikes) . They come in just one size: 16x16. They come in just one format: GIF. But at $45 (USD), they're an inexpensive way to add a little pixel goodness to your personal or commercial web site or application.

You may recognize many of the icons from this very web site. I had started working on the set some time ago, which in turn inspired a mini-redesign, which in turn inspired me to standardize a full set at 16x16 pixels and make them available for purchase (royalty-free), in response to frequent requests from readers who wished to reuse my icons.
There are of course other destinations for buying fully-featured sets at various sizes and formats -- and I'm certainly not looking to get rich off of selling these. Nor will I be focusing entirely on icon design. But creating small icons is fun, and a part of interface design that I've always enjoyed and put a lot of effort into. So here's to trying new things.
I've turned comments on for this post, should there be any questions about the icons, purchasing, etc. I expect there to be kinks to work out in the whole process.
