Yes, the sweet shark and the text are Iron On Vinyl! Why use Iron On? I find that so much easier because the backing is the transfer tape. These are itty bitty pieces that fit on our Simple embelly card SVGs. Give it a try and I bet you will love it too!
I love Expressions Vinyl for all my vinyl needs. Thanks for using my link when you shop :)
