Here is a tutorial that will show you how to use iron on letters on a sweatshirt or T-shirt. I have used iron on letters many times and they are extraordinary. I have never had a problem laundering these letters that stay on even in the hottest water. You can really make some cute shirts for you and your children or as a gift. This DIY comes from Natalie of my “Little secrets” and it is easy and inexpensive for you to make Natalie’s sweatshirt. She does give you a link to where you can purchase the iron felt letters. By the way, they are coming out with more colors, like gold and silver letters that would make perfect tees for a bridal shower or baby shower. TUTORIAL HERE!
