The dandelions I made were meant to grow along the asphalt strip I wanted along the spur. And now, when the flowers had been done, it was time to make the asphalt strip.
I made the asphalt strip using putty. When the putty was dry I created cracks in it by pressing on it, making the putty and the foam beneath give way.
I then painted the putty a gray color, using black, diluted to gray, from an ordinary children's watercolor set. And then it was time the plant the dandelions and add other weeds and grass. Here are few pictures of the result.
