So as many people have been a witness too, my wardrobe consists mainly of raglan/baseball/¾ sleeve t-shirts. I wear them all the time. It's what I do.
My problem is that in some of them the colors were pretty close when I first bought the shirts and after a few washes they're pretty much a solid color shirt. So, what I was wondering is if there is a quick and effective way to restore the color to just certain parts of the shirt. I tried using these markers meant for coloring on clothing but they're completely ineffective. Any ideas on what to do?
