Cricut Cold-Activated, Color-Changing Vinyl Permanent, 12" x 24"

I'm a teacher, and I used the cold activated color changing vinyl to put my student's names on a water bottle as their beginning of the year gift from me. I typically do them every year, but this was the first time I used the color changing vinyl. The kids thought it was really cool, although I used the light blue that changes to turquoise, and the color change was not terribly dramatic. Maybe if I had used a different color it would have been more of a dramatic change. The kids still love it, though!
