I already posted this suggestion on the mod issue page, but now I see you have a github as well, so I'll also post it here:

So, I really love your mod, and I think it would be nice to have something like this for wool as well, maybe you make sheep drop fleece, and you have to process it on a loom, turn it into fabric, I don't really know how you would do this, but I think it's a great idea. Maybe it doesn't really fit this particular mod, but it might be a good idea to a new mod, on the same style as this one. I didn't really know where to suggest it, so i decided to suggest here, sorry if what I'm saying it's not very clear, english is not my first language.

I have an entire fiber oriented mod that will handle wool in that fashion, in addition to flax, hemp/jute, cotton.

This is a nice suggestion, likely suited to be a separate mod though. I feel it would require a different type of wool drop for vanilla Minecraft, much like you added the various hides with this mod. However, I could see it being very useful with the Animania mod, as their sheep don't drop the typical block wool that minecraft does. It would be an interesting process of going through the steps of washing, then spinning the fiber into threads with a wheel, and finally weaving it on a loom. I simplified the actual process to reflect the same Semi-realistic goal of Leather Works.

Additionally, a particularly nice element for pack makers, would be the ability to do some similar things with other modded materials such as flax and hemp. The latter two would actually be able to take advantage of the barrels from this mod as well due to their own respective soak and working processes. You may even be able to call it Textiles as that name doesn't appear to be taken.

CraftTweaker support for each crafting mechanic would be a bonus as well for pack makers to be able to utilize the weaving aspects for a number of items ranging from bolts of cloth, to carpets, banners, etc.

I believe that Leather Works has CraftTweaker support to oreDict the types of hides, based off of the ZS compatibility links on the project page. It would be nice to have the same for a thread/yarn and bolts of material.

I could go on but with the way you have beautifully crafted a simple yet accurate mod with Leather Works I don't feel I need to. Thanks for the time and keep up the great work.
