One way to complicate the clothes crafting (with mods, sadly no skills can be modded), separating steps in to “measure, cut and sew sleeves”x2, “measure, cut and sew body”, “sew the shirt together”
When working with flat pieces like leather, fur and cloth, it’s pretty straightforward and not overly complicated in real life. But one does lose portion of the material from cutoffs, which can be used elsewhere, but that adds additional sewing.
Nalbinding, knitting and even crochet doesn’t waste yarn, but takes an experienced craftsperson to produce anything in decent time.
Once “pause any task” from development plans gets implemented, that’ll also hopefully include tasks longer than 8h.
(There’s an exploit* to utilize the rare masterwork staff into multiple masterwork javelins: have 8 staves of any quality on ground/adjacent, then select to make 9 javelins and last choose MW staff from your inventory, do not have the MW staff on ground!
*last tested in 3.63, might not work in 3.72 or 3.80)
Is it unfair to use such exploit: maybe. But one could contest that a grand-timber-master should be able to produce MW and Fine staves themselves.
