Hi Fiona,
Have you tried the Planar UV map approach? That may allow you to
isolate the top and bottom portions of your turtle shell better for
centering.
Some Steps -
After creating a multichannel shader with your shell texture in full
frame, apply it to your shell object, and then enter the UV editor.
Once there, make sure that the texture display is enabled in the
editor (under Display tab) and check that the mesh color for the lines
are a shade that you can see them over the texture. Then go to the
Projection tab and choose, "Planar, Z axis, No Split, and the vertical
Split Arrangement".
You should see two circular meshes superimposed over one another.
Then, with the blue icon move and rescale tools, position the mesh
over the texture (make sure the mesh is selected--vertices are red and
select a vertice to move the entire thing), and then resize it to fit
over the shell texture map; you should be seeing a live update of
your progress in the Preview window.
You should be able to now render your shell object with the shell map
centered in place. With this approach, the top and underside of the
shell will be the same.

Another approach is that you can export the UV map (this time, a Box,
5 panel mesh) to a 2D paint program and, on another layer, bring in
your turtle texure map and resize it to fit under each uv shell
portion of the map. Then, without the grid layer, you can export the
turtle shell map back into Carrara and see how it fits.
A good program that can help with UV mapping is the UVMapper Classic
freeware program. <http://www.uvmapper.com/downloads.html> There are
some features in it that may help with editing your UV mesh more easily.
Also, here is a list of uvmapping tutorials that may help. The
concept of uv mapping is pretty general and usually applies across the
board:
1) Carrara and UV Mapper Classic -

Well, hope this helps.
Cheers.
