How do you make an arc at the bottom with text???

[discreetthinker]

I am trying to make a logo with a crescent moon and star in the middle, and I want text circling the top and the bottom of the image.
Photoshop allows me to use the warp text option to do the top, but I have no idea how to do the bottom! Does anyone know?? Thank you so much! I can't seem to find a tutorial anywhere either!

I also tried doing the transform option and then choosing the "warp" option, but it doesn't really seem to work for me!
Please help! It is for a t.shirt design.

Thank you so much! I was having trouble trying to figure out the number for the bend...it finally worked!
