The product is relatively easy to work with. You will need to use a ruler, sharp scissors and a knife.  If you follow the guides in the tile, it will look right.  The product sticks pretty well the wall I used it on had a few bump, but it seemed to adhere well.  I had higher expectations as this product does really look like a sticker on the wall.  And, the package states that the amount of tile is 44”x32”,  and I anticipated that the size indicated would be enough to cover half of my wall which is 28”x92”.  In reality, it is a lot smaller in coverage.
