It's used for the Crafted Coarse Gloves in Tailoring. Have to craft the gloves to complete the Tailoring Quest 1 in the Working, Day to Day quest group which is in Learning the Craft. It's weird this is the only Crafted Coarse item that uses it with no mention in the Quest.
I've grown A LOT of Jute too, i'm level 5 Farming, so don't think it is a rare spawn when harvesting.
Would awesome you mix something with the Jute? what profession or activity does that?
