The silver is so beautiful ! They are very thick. It took a lot of effort to cut them. I had to use an X-Acto knife to score it and hammer to snap it along the scored edge. I also used a paper cutter. It was almost too thick to slide through. Using one of those rotary cutting tools may be the easiest method. ￼It sticks very well. Once you put it down, there’s no readjusting. So be careful. I didn’t use grout and don’t plan on it. It’s fine without it. I plan on lining the bottom with Instatrim at some point. I absolutely love how it turned out and I’m so glad I got it.
