[Gimp-user] Creating scroll saw patterns

[Nitram <forums gimpusers com>]

Hi folks, I am wanting to create a scroll saw pattern of a motorcycle in Gimp,
hopefully using a similar technique to this guy on youtube,except he is using
Photoshop. https://www.youtube.com/watch?v=6y-iHDrvIdU
I have a very basic knowledge of Gimp and have used it for simple patterns, but
haven't used layers, apart from clicking random icons to see what happens. I
would like to be able to paint black on top of a lighter coloured layer and swap
between them as he does in the video. Hopefully someone can see from the video
what I am wanting to do and is able to explain easily. :)
