Look in Free Stuff. Link is at the top of this page. Often, free textures are listed as "characters," with names. ("Jane for V3," "Joe for M3," etc.) Generally, free and low-cost textures aren't as high-resolution as the ones DAZ sells. So if you want a photorealistic look, you'll probably have to buy a texture. For low-cost textures, check out Cin's Leanansidhe (for V3) and Nicodemos (for M3), both at PoserPros.com. They are very pale textures with transmapped brows, which makes them very versatile. You can change the skin and brow/lash color to any color you want, in the material room. They are only $2.49 each.
