I've been dyeing some old tops and having trouble getting the exact color I want. Then I ran across a t shirt I used to wear when dyeing my hair and the stains on it were the exact shade I had been trying to get with fabric dye. So, my question is this: is there any reason I shouldn't use hair dye on fabric? I'm not looking for something that will last forever, and it's something with no bleach. Anyone tried anything like this?
Thanks!
