Is there any need for distinction between thread, fibre and sinew?

The set is rather bloated, but I would still keep sinew as separate from thread. It would be rather immersion-breaking to sew cotton sundresses from dead animal bits. At this point I'd rather drop sinew than merge it into cotton thread.
Plant fiber could transform into cotton with no real issue. It's similar enough.

Strings of different length could be dropped for quantities of thread(/sinew/yarn/fiber). Same for cordage pieces - plants could just drop cordage instead of "withered plant", with long cordage not existing.

One problem I can foresee with dropping various lengths of string for thread is the quantities involved. Depends if people are happy having very big numbers.

If it is a problem. dropping a zero across the board would help with that. But then one would have to adjust consumption values for sewing, the maximum amount of ammo in a sewing kit, all recipes, etc

Perhaps turning fiber into thread would be a decent start.

Long and short varieties could be transformed into one item respectively.

One long string breaks down into 6 short strings.
I'm thinking the generic replacement should take the middle ground. With 'string' representing 3 short strings or half a long string.

The same would apply for cordage and the rope varieties.

1 thread -> thread
2 plant fiber -> thread
3 short string -> string
4 long string -> string
5 short cordage -> cordage
6 long cordage -> cordage
7 short rope -> rope
8 long rope -> rope
9 short cordage rope -> cordage rope
10 long cordage rope -> cordage rope
11 sinew -> sinew

1 thread
2 string
3 cordage
4 rope
5 cordage rope
6 sinew

11 candidates down to 6 isn't bad. Collapsing this further results into some problems though, particularly with the crafting of cordage, as it has a variety of sources and treating them all as cordage would create more clutter.

There are more items that could be potentially collapsed:

scrap metal
chunk of steel
lump of steel

small metal sheet
sheet metal

heavy stick
long stick

These are all essentially the same item, just in a different shape or size.

One idea would be to get the average for volume, weight, etc for these cases, and have the generalized equivalent replacement take on those values

If that makes sense, I could do it. Here, most likely, you need to change the drops and delete / change the recipes. Everything in json if I understood correctly
On my own I will add that I support the reduction of unnecessary materials
