I ordered these and was impressed. My husband cut them with a table saw and we bought some adhesive and appllied them to the wall. Next day - I filled in the seam with joint compound/ let dry / sand. Had to do the fill in part at least 4 times to try to hide the seams. Painted a gray like in the photo and looks good. Lots more work than I thought with filling in the seams.
These are spectacular on the wall. However they came loose in a box ( the manufacturer's box) which is slightly too big for the tile, and there is absolutely no packing or cushioning, so the corners had all been rounded. You can work round this but it makes the installation on the wall a little more laborious and time consuming if you want things to look seamless. Overall a great look, and I will buy more for a larger feature wall.
