Or skip GIMP completely, load the original bitmap in inkscape and
manually (or maybe automatically) trace what you want. I have done
something like that before. It's a lot easier if you have a graphic
tablet or screen pen of course.
There are some programs (GIMP included) where you can turn a picture
into a line drawing (using less data bits), by adjusting a threshold
where it determines what's blank space and what's imagery. In essence,
turning it what looks like an old fashioned photocopy, or fax scan.
Though, you may not want a simple ink/blank rendition of your image.
