Tea Dying Failure

If you remember correctly, I purchased a skirt from Goodwill that had a fun and quirky pattern but was colored rather Easter-y for my tastes.

I attempted to dye it using tea, which I read could work because the fabric wasn't that dark.

Unfortunately, it didn't work.  Perhaps the type of fabric was wrong for tea-dying, or the tea wasn't dark enough when I made the attempt.  I have to say that the skirt did have a nice lemon scent afterward.  You win some, you lose some.

I broke down and bought red dye, because it was the best available in my area.  I might mix dyes and go brown, because I wanted a neutral to begin with.  We'll see.

Has anyone been successful with tea-dying?
