Clothing
From Cantr II Wiki
Clothes currently serve no known purpose in Cantr, other than for roleplaying purposes, and for demonstrating wealth. Generally only the elite characters of Cantr wear any mentionable clothing, except for some regions where clothing is considered more important.
Types of Materials
The main types of clothing in Cantr are hemp, silk, cotton, and wool.
For cotton, you're going to need to use a cotton gin to create cotton fibres out of raw cotton, firstly.
You will need to turn the cotton fibres, raw hemp, or silk cocoons into cloth. This will require a loom.
