These are TERRIFIC! I've made use of a similar set that I go from someone years ago that I still make use of.

Looks like a good idea. Where is this type of cobblestones located?

looks like a good idea !

Nice. Sadly it doesn't look like any of the US stockists stock many of the molds they make.

Ummm...on the street?

I like silicone molds are very cost effective,Lucky Models have all J'S works stuff. This is a good question .... I have traveled a lot in Europe but in natural stone I have never seen a similar road pavement, cubes and rectangles yes, but hexagons only tiles (very popular between the end of the 19th century and the 40s) or concrete but recently produced for paths,driveway or under a patio, having worked a lot with natural stone and in the old way by hand without the help of machinery, I feel quite sure that if there are roads like this they must be at the entrance of a very important building or something similar to a palace because between labor and the waste to work the stone with that shape you have to have the money that comes out of your ears ... especially of those sizes, perhaps in places like Versailles The other mold pretty much all over Europe
