This project turned out amazing, but it took a few applications to get it right. I didn't realize that the Oracal 651 really isn't intended for wall applications. I first cut the design out in black Oracal 651, and the white in ShineRite. The black Oracal peeled off within a few hours. The white ShineRite was very tacky, and stuck without problems. I had to go back and replace the black with ShineRite (Oracal does make a wall vinyl, but I replaced it with the ShineRite, since I knew it would stick really well.) I would highly recommend only using a vinyl designed for wall graphics and not the 651 for wall art.
