Iron-On Transfer DIY Graphic T-Shirts under $5 - The Pretty Life Girls | I am a little embarrassed to even share this DIY Graphic T-Shirts tutorial because it seems like a total no-brainer, but MAN, did the final products turn out great! It literally took about 10 minutes per shirt, and the total cost ended up being under $5 per shirt. All you need is a blank shirt and printable iron transfer paper, and you can make a custom shirt with endless possibilities!
