For me part of having this blog isn’t just the content I post on it, it’s also very much the creative process of customisation. Here are some places I frequent when looking to update my graphics.
My Fonts – great place to find free fonts
Font Squirrel – Commercial use free fonts
iStockphoto – sure you have to pay for things, but there’s some really cute illustrations available.
Obsidian Dawn – love the photoshop brushes here.
The Graphics Fairy – for all your vintage picture needs
More to come as I think of them.
