Color Weirdness/Double Faces

I’ve been working on this for a while, and when I hit render, I noticed some ‘checkers’ on the model. I paid no heed. However, now I have my image/UV, and the problem is still there.

I discovered that somehow, my model has two faces for each face. Problem is, I have no idea how to go about fixing this.


Blend file will be provided if requested.

Sounds like you just have duplicated your mesh. You need to delete the extra set of vertices. In Edit Mode, hit A to select all, then W>Remove Doubles.

That works. Thank you, K Horseman!
