Editing Textures Using Wand

asked me to make a tutorial on how to do this. I had never done this before so I went looking for help.... Nothing. Nothing concrete and put together, anyway. So I downloaded a few textures from QTextures (here is their [link] ) and just kinda winged it.

For it being so freaking simple, there are no full tutorials about it. And I looked on Google, Yahoo, and Bing.

So I guess this is the first one? Yay!
