If you use Adobe Illustrator you probably know about custom brushes. Here is a set I use to create soft shadow effects in vector art. "Colorization Method" is set to "Tint" so you can set the stroke color to whatever you'd like.
Effects achieved with transparent fade brushes, in Adobe Illustrator CS5.
After downloading the file, go to the Brushes panel flyout menu and select "Open Brush Library>Other Library".
