It’s quite tricky to do actually, even as an adult. You have to be so super careful of the wax as its very very very hot.
Im a bit upset that the wax spread when I was ironing it off, but that’s because the teacher who mixed the dye, didnt fix it. That’s what im blaming it on anyway. 
soooooooooooooooooo cuuuuuuuuutee!!!
