Okay, I have put it off long enough. I have to learn to uv unwrap and texture map.

I have decided the best approach is to take baby steps. Here is a very simple dart model. Shaders of the barrel section are just simple procedurals.

I unwrapped the fins using automatic map, layed them out and took a uv snapshot (jpeg). Next, I created the basic vector graphics for the fins in illustrator and then brought them into photoshop along with the uv snapshot of the fins.
