How can I make my own tin sign?

I really want to make a legit looking sign for a christmas present. I would want one of those tin signs that usually have some witty remark about coffee, but I have my own design I want to put on. Is there anyway I can do that? Or is there another kind of sign that looks similar? I want it to look good. Not something on a piece of paper and framed.

Hello Amanda47.
You can contact any local welding shop.
They can cut a piece of light gage sheet metal any size you want.
Personally, I would recommend 14 gage steel or aluminum.
It is about 0.77 thousandths of an inch thick, about the thickness of the
cardboard back on a writing tablet.
An air conditioning service can provide galvanized / tin material but I think it takes
a special / acid wash/ primer conditioning to make paint stick to it.
Both places can round the corners and drill mounting or hanging holes for you.
