One of the top voted ideas was to produce a set of city streets. We've always loved the fan style of cobblestone street, so that was our first set to go for. These are super flexible, as you can do streets, but also create a really pretty city or market square with them.
The initial cut of this set will eventually include curbs, sidewalks, guttering, alleyways and probably a few more styles of street.
