Apply texture to mesh that has been extruded I'm super new to blender. I'm trying to build a room and I am trying to apply a texture to one of the walls. I had to extrude this wall to get it to the right size, so there's a few edges/faces that make up the entire shape. If I try to apply a texture, one face is textured differently than the rest of the faces.

If you see here, I have the entire plane selected, but the UV editor on the left only slected a portion of the texture. I have no idea why, so that's why I'm asking you guys how to fix this.

So you can see here that the bottom of the wall looks different from the rest of the wall. Can anyone here help a noob out?
If you make a change to your mesh you will need to UV Unwrap it again.

In Object Mode Apply the Scale Ctrl + A > Scale. 

Also, you could use the Project From View method of UV Unwrapping since it's flat. Just make sure your looking at it straight on.

A quick tip on Modeling the wall: Unless you plan on extruding "out" geometry your mesh would be much "cleaner" if, in Edit Mode,  you just selected the bottom two vertices (or top two) and pressed G + Z to grab them and move the only on the Z Axis. Then your left with a simple rectangle. If you Extrude the mesh down you are creating extra vertices and in complicated models that will increase render times unnecessarily.
