Code:
turf
grass
icon = 'landscapes.dmi'
icon_state = "grass"


turf/pavedpath
middle
icon = 'pavewalk.dmi'
icon_state = "right"


Problem description:

May be a novice question, but if i place middle on grass, grass is no longer there. I want grass to be below middle
Tried messing with layers, making one of them layer one and the other layer 2 but it does not change anything.
Open your map, go to Options>Click Behavior and change the option to insert instance instead of replace. Alternatively, you could just hold control while clicking to do the same thing, but you would have to do this every time you wanted to place one object over another.
