Other than internal consumption, the focus of cotton spinning industry, which had adopted new spinning tools and assembly-line work, was on export to earn foreign exchange.
While waiting for their home-grown cotton to ripen, a large amount of cotton was smuggled in from the warm south by Castilian black-market traders, who exported processed cotton fabric. The profit margin was used to purchase essential items for daily life such as livestock and salt, as well as raw materials like coal and cotton — a primitive and not-so-perfect cycle, but the enormous profits gave the elves a blissful sense of satisfaction.
There are always two sides to everything. The bright side of the coin was the elves' smiles, the dark side was the mottled tears and faint sorrow of the cotton spinning craftsmen in Argentoratum.
