The easy way would be to scan one, or get an image of one. In an image 
manipulation programm, set the background as transparent usingan alpha channel.
Use a polygon and map that image on it.
You should also create a bump map from the image and use it as a normal pattern 
to give the feather some relief.

Another way would be to use the gray level bump image as a height_field and use 
the colour version as pigment.
