Super happy with our project! This went up incredibly easily and fast! We covered three sides of a 22’ island in our commercial space (for a service counter) in about 6 hours. Pieces scored and snapped perfectly with a common utility knife. We sorted the lighter and darker colors, but honestly I don’t know if it really mattered. There is nice variation in the tones. We did not use a j-roller, but we did press each piece securely. Everyone that has seen it raves! We still have a few trim pieces to add to tidy up the corners but otherwise, this project is done! We have had zero issues with them adhering, btw. And these went up over raw 12” plywood.
