This is a great way to recycle kid's old clothes!
I used acrylic craft paint and mixed a small amount of textile medium to it.
Then carbon copied the logo that we wanted onto the shirt.
Don't forget to put cardboard between the front and back of the shirt to prevent bleeding through. (I used a cereal box)
Follow the directions on the textile medium bottle and heat set the fabric after it is dry.
The darker colors will fade some in the wash but letting it set for a week before washing will help.
