for cotton I'd be choosing between (alphabetical, not in preference):
Cloak - possibly made of cotton
Greenhouse - could grow cotton?
Plastic - another type of material
Polo - cotton shirt
Sweat - sweat pants, picking cotton in the heat, sweat shop
Greenhouse is a bit risky, maybe Nich knows if you can actually grow the stuff in one lol no need for us to take any risks we're miles ahead and don't want to give them a free word
