Whenever I found an Iron On, I immediately would begin begging various family members to help me transfer it to whatever plain t-shirt I could find. Sadly those t-shirts were often the cheapest undershirts that money could buy. So the poor iron on was usually short lived. Since most iron ons I got my hands on were pretty cheap, it was not a huge deal, since they would not have lasted longer than the shirt anyway. I did not realize that at the time though and whenever I needed to retire one of my awesome custom tees, it was with a heavy heart.
