Kinda hard to explain or teach. Basically you make the texture and then make it seamless. (To make it seamless I just use a paint.net plugin called seamless texture helper and then patch up tiling errors with photoshop patch tool) Making the texture itself is a bit more complicated, can't be bothered to explain it in detail it's 4am.
pfft.
I go oldschool pixel by pixel.
Also speaking of tiling, I did the plank texture blind, and just today I patched couple of them together to discover that I managed to do it without tiling errors.

don't know about the rest, tough

also if you guys happen to need an artist or something, I'm up for the job since I really don't have anything to do

Aww, the texture creation part is what I wanted to know xD
If you care to when you have the time, I'd appreciate it :3
