Hi! This stays on pretty well for "decorative" / art dolls! I haven't had to re-apply any blush for the dolls I've added blush on, and it has been about a half-year for some of them. They still look the same! If the toy is for a child to play with, I would not recommend using powder blush. My guess is that it'd need to be reapplied after some play/use.
Thanks for the video! What brand of blush do you use? Is it blush for people's skin or blush made specifically for crafting? Is it washable, or will it come out with water and soap?
If you are looking for a way to add blush that is permanent, you may need to try some permanent fabric markers or paint. I have never tried that myself though, so I'm not sure how it will turn out! Sorry if that isn't very helpful!
Hi, the blush does fade away with washing. I would recommend this for more of an art doll and not a doll that would be played around with and endure lots of use. If you'd like blush that doesn't fade, it might be worthy to look into fabric paints or something that stays on better. Hope this helps!
