I decided to dye it to match one of my favorite pairs of PJ pants (since I always get teefury grab bags in PJ shirt size), so I went and picked up some dye. I did the dye in the sink and had so much fun with it. It looked so cool. And yes, the water is steaming because it was supposed to be hot water.
After filling the sink with hot water, I spent the next 40 minutes constantly stirring and sinking the shirt into the dye.
The finished shirt is just gorgeous! I can now enjoy this grab bag shirt completely!
And if anyone is curious, I used violet RIT dye. The picture below is the closest to the color of the shirt, and it's almost exactly the same color on the bottle.
In the future I won't hesitate buying awesome white shirts, because now I know how easy they are to dye.
