UV mapping in blender... Anyone?

[Treedeejoe]

This is a pain. I'm using the UV map feature in Blender on a cube like image.
My difficulties lies with some of the surfaces are not pointing in the same direction so that this inside of the cube (which is visable) has clear spots.
The out side looks good, but how do you flip the indivdual faces?

WOOHOO!!! I've figured it out. In edit mode, select the face that's in the wrong direction and hit the W key and under the menu press "flip normals".
Success. It's so wonderful.
