When I do a frame for a fractal, I make it up within the fractal program - In my case, UF. There are several coloring algorithms available for UF that will create frames, or you can make your own from scratch by using the clipping transformations. The image linked to here is an example of a frame created from scratch. But for getting started, the tutorial Jock mentions above is excellent.
