Stable income: Somewhat stable

Starting a T-shirt business can provide a source of income, but its reliability varies. While some individuals achieve consistent earnings, others experience fluctuating sales. Success depends on factors like marketing, design quality, and target market. Overall, it can be moderately stable with a decent baseline income, but there may be unpredictable periods. I'd rate it a 3 out of 5 because while it can offer steady income for some, there is still a level of risk and variability involved.
