Adds large stone bricks. To make them, place two stone blocks of the corresponding stone or sandstone type in the crafting grid. Then place the two resulting nodes adjacent to each other to get a large stone brick.
It's quite beautiful
Thank you AwesomeDragon97.
Subtle and clever
Placing a large brick node next to a large brick node horizontally creates the appearance of a brick that is two nodes wide and one node high.
This effect is subtle and looks quite nice with walls that are several nodes high.
