Looks Great
I purchased the pantry and laundry room stickers.  My doors have ridges on them to make them look like they are wood so I was concerned they wouldn't stick.  I sanded the area a little bit since there was a heavy gloss paint covering the doors, wiped clean and applied sticker as directed and it is awesome!  It's been about a month and there is no problem, no curling and looks great!  Highly recommend.
