Just got a reply from her:
It won't come off easily.
You often see it on your T-shirt, jumper, etc.
I wanted to test it Whether stick before sewing of stick after sewing. and size check.
And I have to run a lot of machines to stick it, so, I didn't use machines, I just use iron. so, It is not perfect.
you can see perfect sticker on final sample.
and You can see it in my another brand website.
