Stained glass, tattoo, and cartoon patterns are available in the milllions online.
if you do this style the world open up quite a bot and its fun. of course it has its limitations but also its advantages.
Do enough of them and you will be able to take a picture of something and make it into a pattern.
The key is the black lines like Dicks first example. All cartoons have that. Once you start seeing these black outlines in things you will see them everywhere and be able to make your own patterns.
Fun to experiment with.
You do need to find some small blades and drill bits though. I use 2/0 jewelers blades, They have no reverse teeth so make a mess on the back but I no one sees that so does not matter.
I use a jewelers screw type drill with #72 or 73 bits trimmed down just enough to drill through the wood. Longer and they will snap quite often.
