For most people creating Fav Icon for your blog or site is a difficult tasks. Even for illustrator and designer, creating 16×16 pixels icons is a stressor. It’s because they are not proficient on creating image in tiny pixels and in 1:1 size.

If you have a large logo of your site, scale it down to around 50 pixels, and use Favicon Generator to make your fav icon ready to use.
For pixel-pusher, the site also has an editor. You can create anything what you want. After serveral minutes I’ve made this “skull” icon.
If you like it, grab the icon here. Feel free to use for your project :-)
Want a quick grab, go to the gallery page, and pick the icon.
