Stamped concrete.

Wire screen should be fine. Are you doing the stamping? Ever done it before? Who has the stamps?

I agree with Bal. I would like to add if you do use wire mesh or any other Mesh pleases use "Chairs" under the wire to hold it at the correct height. Too many times people use rebar/Wire mesh and it ends up at the bottom on the Crete from being walked on during the pour and it ends up doing nothing for the pour
