Following the directions on the bottle I dyed my shirt in the utility sink in my laundry room. I have a glass pot I use for dying.
I didn't stir it as much as I should have so it looks "splotchy". But I like it. It gives it a hand crafted look.
The shirt wasn't 100% cotton which I didn't realize until after I dyed it. But the stitching stands out a lot better now so that's good.
