Where can i buy those thin wire like signs?

Question:I'm not talking about the thick ones used to sell homes like the ones they have at Home Depot.

I want the smaller ones that people place on the corners of intersections when they advertise their business or garage sale.

Are these signs just home made? If i can make one from simple materials information on how would be appreciated

Answers:
Some are homemade and some are store bought. Home centers sell the generic ones (garage sale, home for sale) but some people will take an old one that has been left on the road (old garage sale sign) and cover it with poster board to make their own. If you want a nice, customized one, you will have to call a sign shop (they're pretty expensive).
