In addition to the recipee above, there is appearantly another recipe for making Cotton Thread. I saw a Japanese player use an Earth Crystal and got 6 Spools of Cotton Thread as a result.....does anyone know this formula?
I'm sorry, I don't think it actually was an earth crystal. But I've definately seen people making 4+ Spools of Cotton Thread at once, which you obviously can't do using the Saruta Cotton recipe.
