umm, a little more detail on the project please...
It would be helpful if we knew what 3d program you are using to do this...
Are you making the UV's yourself or are you using something already created?
and also can you give us screenshots of your problem as well...
and for texturing i would try the texture i have posted in the other thread,
here is it... (Help with UV's)
if you don't want to use that texture to help you place your checker texture...
then put a pink dot in one of the squares, this will show you where your texture is being placed on the model.
and go from there.
