Welcome to Vertical Slabs

Vertical Slabs is a mod that adds vertical slabs to Minecraft. They work in a similar way to vanilla stairs, connecting nicely to adjacent vertical slabs.

Crafting

Each slab can be crafted with its vanilla normal slab counterpart, and can be crafted back into its vanilla normal slab counterpart as well. Additionally, you can use a stonecutter to craft vertical slabs from stone and similar materials, just as you can with the vanilla slabs.

Updated to 1.16.4. This should fix issues with slabs not connecting to other types of slabs.
