Been following tutorials on creating materials using shader nodes. Went off and did some experiments of my own. Two things I’ve learned so far:

• Use noise to distort the lookup position of other noise or texture generators.
• Ask yourself: ‘What happens if I put a color ramp after my noise?’ Then put a color ramp after your noise.

Unfortunately there is some kind of driver issue or something card that causes my Cycles GPU renders to be all messed up when I use certain shader functions. But EEVEE is pretty good too with raytracing enabled and a lot faster. So I might try to use it more.
