Here's what I have so far. I think I overdid the tea, but will see what it looks like when it's finished - then I can wash it and see if it fades a big. The border is bigger than I first thought of, but the scale of the piano fabric seemed to need that. This is a wall hanging for the wall behind my piano - I teach 23 students after my day as an elementary music teacher! There are 4 word panels total so this is half of it.

I like it! If you wanted to do that in a bed quilt, how would you stop the tea stains from washing out eventually? Or can you?

I don't know about long term use of the tea dye. I only did this because it was a wall hanging. Seems like there are references to it early in this thread though. I did iron it right after spraying it and that should set it for a while.

I also use coffee too , I save any unused coffee in the coffee pot in the fridge when I know I am going to dye something. After all coffee is getting expensive!
