What this guide covers
The official store confirms cotton, linen, wool, silk and velvet; this guide helps you compare the materials without inventing hidden stats.
Source-grounded approach
The official Steam description confirms fabric selection, pattern cutting, sewing, decoration, customer commissions, reputation and coin. It does not publish a universal best build or hidden numeric formula, so this guide does not invent one.
Next step
Use the live Steam store and in-game prompts as the final authority when a detail changes.
