From my own experience of trawling the web for a nice easy way to make a Female 40K Eldar Farseer, I know that there’s no shortage of people out there looking for ideas or inspiration.
Unfortunately, until recently, most of the suggested ways to build your very own lady psyker have involved a great deal of green stuff work, or resulted in something that didn't really look like a Farseer. Suggestions such as putting a Farseer head on to a Howling Banshee body and green stuffing on a cloak for instance, might sort of work to portray your intent, but I've never felt like they really look the part.
