Chalk

https://www.curseforge.com/minecraft/mc-mods/chalk-fabric

Fabric port of the Minecraft mod Chalk by mortuusars with some additions and 1.17 adjustments. Thank you very much for creating the original Forge version and the permission to port Chalk to fabric!

Adds two simple types of chalk to aid you on your mining journeys. Never lose your way again.

Adds:

• Chalk: Crafted shapeless with 2 Calcite
• Glow Chalk: Crafted shapeless with 2 Calcite and a Glow Ink Sac

With chalk, you are able to mark the surface of every full block. Hitting the corner of a block creates an arrow pointing in that direction, hitting the center creates an X. Marks from Glow Chalk can be seen in total darkness, perfect for caving action!
