Hello again fellow Houzzers... We are putting the final details on our 'subtle' retro kitchen design. There is a long panel (about 30"x 8") just below the sink and above two cabinet doors that I'd like to put a little faux venting detail on. I've seen designs that have three lines in them, with the center line being the longest, but the harsh rounded edges are off-putting. I've seen a perforated diamond design....but maybe it was in another life because I can't seem to find an image now... Any help that includes visuals will be most appreciated! Thanks all!
