How can I get my texture to appear correctly on my cylinder? I am trying to make a simple casino chip.  I have the textures for the face and the sides created with photoshop. The texture on the face appears correctly, however, the texture on the side looks awful.  I just want there to be the same number of white stripes on the sides of the chip as there are on the top and in the same spots.  In other words, I want the stripes on the top to extend down the sides.  How can I accomplish this?  The cylinder in blender is 39mm in diameter and 3.9mm thick.  The texture in PS is 3.9mm wide by 39mm tall. This is what I have so far...
This is happening because each side face on your cylindrical chip is having the texture applied to it. What you want to do is UV unwrap the whole edge as one strip rather than having a bunch of overlapping faces. To do this you need to mark some seams to tell blender where to separate the mesh. Mark seam the top and bottom circles and then one vertical edge (You can do with by pressing Space and then searching for "Mark Seam"). 

It will look like this:


From here you should select your whole mesh with A and then press U to unwrap.

You final UV map should look like this:


Your chips top and bottom textures should be aligned with the circles and the side texture should go across all of the side faces.
