One of the newer features of Inkscape is the ability to blur the edges of things. Pretty cool for a vector-based program, eh? I tried out the blur feature on the simplest thing I could think of: Clouds.
It's really simple to make clouds in Inkscape:
1. Use the freehand tool to make a cloud-like outline.
2. With your cloud selected, choose the option Fill and Stroke from the Object menu.
3. Make the fill white and the stroke non-existent (x).
4. Use the Blur slider at the bottom of the window to adust how blurry you want your cloud. You may even want to make the cloud slightly transparent by using the Master opacity slider.
5. Once you are satisfied, have fun experimenting with more clouds!
Here is my experimental result:
