When reading through the project page for Leather Works, it appeared to me that the CraftTweaker functionality is built into Leather works. (EDIT; based on the links for the BWM.zs and Aether.zs)

val string = hide.withDamage(#);

val oreHide = <ore:resourceHide>;
val oreRawHide = <ore:rawhide>;

oreHide.add(string);
oreRawHide.add(string);

I'll be brutally honest. I am a complete and utter pleb when it comes to CrT. Is this functionality that you've added to Leather Works to work with CrT? Since I am learning, and studying the first 3 lines of the above I am willing to guess that it is. And hope that you could confirm if I'm right.

Additionally I was curious if you had any plan to include CrT functionality with the barrels and drying rack. And possibly some documentation if you do have native CrT functionality.

Awesome mod all the same really think it help mod packs become more immersive early game. Thanks for your time and excellent work.

This is just basic ore dictionary use in crafttweaker. This could be done as a script to modify any ore dict entry using base crafttweaker.

Generally speaking adding crafttweaker support means allowing users to change recipes for additional crafting mechanics. Like the barrels and such.
