I bought 5 packs and it was just enough for my large kitchen. At first it was nerve wrecking but it is easy peasy. It’s just laying puzzle pieces together. I used a utility knife with a fresh blade and a cutting board underneath so I didn’t cut my counters and it was a breeze. I had to do 2 layers of the backsplash and above my stove took 3. I would do it all over again, it was a ton of work but so so worth it! The quality is excellent and does not have the “sticker” look or feel. Take the risk you will thank yourself
