While I was building my city I was using Masonite for my streets and curbs and realized that while it worked well for what that application it was not a good system for most places so I started looking for something that was much easier to work with. I found that Dick Blick has 1/8 inch foam core board easy to cut and make into the proper shapes but the edge looked wrong so I got some evergreen .010 by .125 styrene strips anbd glued the strips to the cut edge with CA. Next time i will use Elmers or some other glue since I wound up with styrene and foam core pieces glued to all my fingers(queue up circus music) then I painted the whole deal with some latex paint I bought that matches the Krylon camouflage Khaki colored pray paint (which matches the color of concrete perfectly) Since i have a bunch of odd shaped curbs to build in my amusement park I was quite p[leases with the way the curbs looked afterwards and since the styrene is so thin it bends around curves easily. The only draw back was I had to buy 10 huge sheets of foam core but it was only like $35 for all of it.

The town fathers decided even though the sheriff can't be everywhere at once, they need to expend some taxpayer money.
