Small tomato plant lattice?

So I am growing a small tomato plant it's about a foot and a half tall and a foot wide, I need to find some kind of tomato plant lattice or something to help it stand when the tomatoes start growing. I have looked at walmart, home depot, and amazon but I can't find anything for a tomato plant? The only thing I found was a 6 foot lattice...... where can I find one? Is there another name for it? Any homemade plans?
