The come with a padded double sided tape but I also added some adhesive.
They only had one size and it wasn't 3" like my evergreen beauties so I changed the pattern. Just stuck them right over the existing tile.
BAM! They aren't bent that's just my mad foto skillz. They aren't 4" so they don't line up perfectly with the white tiles. But anything is better than green. Especially when that anything only costs $20
They are super easy to cut for places like outlets. I used my kids scissors cause I was to lazy to go upstairs and get mine.
Next up hardware on the cabinets!
