Now I've looked on google for a while and I couldn't come up with a good skinning clothes tutorial. I want to make a few reskins but I am in no knowledgable about skinning. Does anyone have some tips?

I'm assuming you have Photoshop 6 or higher.
Now, I'm no expert player skinner, but from what I understand you take the color you want, add a small amount of noise for texture, then to get the wrinkles you make an initial line with the burn tool. make another dodge line, ever so slight, above the burned line to give it depth. For camoflauge it's probably best to find a picture of it then edit it in Photoshop

Wow, that really helped me out a lot. Thanks. I notice a huge difference than my previous attempts. Anyone else have more?

i too would like to know more about skinning; since i don't know diddly squat!:D

Yes! Like skinning the metal bits on guns. Any tutorials or tips on that?

Most texture artists are reluctant to give away how they make their textures. I'll give you some tips on lighting, though. Always use the dodge tool on highlights, as to not make an opaque white line, and use it with around 38% exposure. For burning use it on highlights as well, but around 28% exposure.
One thing I see that is lacking from most skins today is the lack of edges. Edges should be properly highlighted, then slightly sharpened, since they are the places that are most prone to being scratched. To achieve this look properly, take the dodge tool on 1 or 2px, 15% exposure, and dodge on a straight line on the edge. After you've done this take the sharpen tool with the blending mode as Lighten and 15% opacity(exposure). Choose a soft brush and sharpen right next to the line until it becomes fairly bright and in some areas, usually the far end of the corner.

Not to contradict Mike, but sometimes Dodge isn't the best way to do lighting.

Depending on the color and/or texture, sometimes using the Lighten tool will do a better job than Dodge. If you use dodge too much on dark colors, it will smear the texture and create purple and green areas, if it gets to that point...undo the dodge tool and use a very light opacity Lighten on white.

And don't over-lighten your edges. Although it's nice to do MINIMAL highlighting, if you do too much, it will look awful and stick out like a sore thumb in-game.
