What this guide covers
Start with a simple commission, choose fabric deliberately, then use the sketchbook, cutting table and sewing machine as one connected workflow.
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.
