Currently there is no point in bolts of cloth in villages since UrW doesn't provide means to make clothes out of them. Once clothes making makes it in bolts of cloth would make a lot of sense.
Well, making cloth is very labor-intensive and also requires a very particular skillset (spinning + weaving can turn out very different results depending on the skill of the manufacturer), so it might not be feasible to add cloth-making as a function anytime soon. But I don't see why the current "make fur/leather clothing" code can't be utilized so characters can make a shirt or leggings or whatnot out of bolts of pre-woven wool / linen / nettle cloth.
Scissors/shears should probably be included when sheep shearing makes it into the game, with the attendant clothes making (Ah! some warms socks and mittens for the winter!).
I would like to see
nalbinding make it into the game someday... it's a technique a bit like crocheting, used to make socks and mittens in Scandinavia since the Viking era and probably before then. Scraps from what look like mittens made with nalbinding have been found in Finnish graves as well, the most famous example being from the Eura grave find:
A fragment of what is thought to be a mitten, from the "Eura" find. Included in a paper by archaeologist Krista Vajanto,

Unlike spinning, it doesn't require a lot of dexterity or skill or even a huge time commitment to turn out a wearable product, so I think it's well-suited to the average URW adventurer who doesn't want to buy their mittens in a store, or maybe who is just bored on a cold winter's night.
Sickles were probably the tools of choice for grain harvesting during the UrW time line, as I think scythes were introduced later in history.
I doubt any but the most modernized farms in Finland were using scythes for harvesting even into the 20th century, as the design of the most commonly used scythe in Finland does not seem to have been conducive to the harvesting process. (Of course, many farms in Finland now are probably using machines to harvest). Correct me if I'm wrong, but any harvesting scythe would need to have a cradle of some sort, to catch the falling stalks of grain so that the harvester could lay them aside neatly, without scattering stalks / single grains all over the place and wasting a lot of precious crop yield.
In fact, not only does the Finnish scythe seem to have no cradle (as described at
this blog post), but it also doesn't have the second handle seen in the Austrian scythe, making it even less suited for reaping grain. It's quite awe-inspiring to watch the Finnish farmers make hay with it, though. The following video (which can also be seen at the above linked post) was filmed in the early 20th century, and shows Finnish scythes in action:
