Hi! I bought most of my iron ons on Etsy. They did stick well but they're not always perfect. I've been buying iron ins for my kids for years and they always seem to be hit or miss. Just make sure to not stretch the iron on when your kids are putting them on. The two I used for most of mine were arewethereyetdesigns and novelteedesigns on etsy. Let me know if you have any questions!
