Try as I might, I could not find a cute set of social media icons that used the new StumbleUpon logo, so I just created my own. Once the icons were designed, it was pretty simple to change the colors, and I've created a set of icons inspired by the Pantone Fall 2012 Fashion Color Report free for you to use on your blog!
Each icon is in .png format, and is 100 pixels square with a transparent background outside of the circle. Using the height and width attributes in your image html code, you can downsize them to whatever scale best fits your blog. If you need any help doing this, don't hesitate to ask. Please note, the downloadable icons are truer to color than the collage above.
You may download the icons, organized by color, using the link below. These icons are for personal use only. If you wish to share them, please link back to my post and not directly to the download site.
