Emelrene ... coastal centres might be able to absorb some imports of wool. Melderyn is both near and traditionally well connected.
I doubt, though, that Harnic wool will travel much farther in raw form.
In other words, a lot like the England/Flanders connection on Earth.
As far as I'm concerned, THE major export of the island of Harn is wool, and much of it goes straight across to Emelrene who turn the raw wool into spun wool. Whether they make woolen cloth is a matter for more debate, but it makes sense.
This doesn't mean Harnic merchants then bring the cloth BACK to Harn in any kind of volume; home-grown industry will supply the island's markets with woolen cloth. The very BEST wool (ie, the finest grade) will probably end up as royal robes throughout Western Lythia.
I have some thoughts on how the raw wool makes it to Emelrene; after all, it has to travel from where the sheep are all over southern Harn (from Kanday all the way to Melderyn Island), but that's for a different post.
My point is that, like medieval Flanders or in our case Emelrene, if you have the capability to turn flax into linen, you also have the capability to turn raw wool into woolen cloth; same principles, same equipment. Well, mostly (I'm sure there are experts here on the forums that will tell me I'm over-simplifying). But the reality is that spinning and weaving "stuff" is pretty much the same, regardless of what the "stuff" actually is (flax, wool from sheep, llamas, goats, or yaks, or something more exotic like silk).
