For those who don't like getting lost in caves, there's the chalk Mod. And for those who love being engineers, there's the Create mod…
so since Create 6.0 brought cardboard, why not include its recipe in Chalk?
But for those who don't know how to do it:
Something like this: C:\User\ .minecraft\saves\new_world\datapacks
Just leave it there, done!
This datapack includes the recipe unlock from the Create's cardboard achievement, and it's included in the recipe list of the original Chalk mod.
Therefore, you need both for this datapack to work.
