The star quality of stuff that you put into a processing machine like a keg , loom , etc . has no effect on the quality of what is produced . If you want to maximize your profits and have a limited number of spots to process your goods , sell the higher star quality goods and process the ones with no stars . edit I should add that while the star quality doesn ' t matter for processing , it does matter for gift giving in terms of the number of friendship points you earn , and by a considerable amount . <| sep |> Total transparency .
