This Basic Grey Magnetic Mat? You need it. Yes you do. I contemplated buying it for the longest time and finally took the “plunge”. I don’t know why it took me so long. I LOVE it! I don’t scrap in one place I like to move around so it’s perfect for that but even if I did stay in one place I love that the magnets can hold all my layers in place while I walk away to do other things. I am SO glad I bought it!
