We're covering over cork ceiling in the entire house (yes, cork...from 1962) in a new purchase. The ceiling is a slight sloped vault with beams, and I need to cover the cork that was applied between the cedar beams. I love the look of tongue and groove or even slat board but doing it one piece at a time is expensive. Can anyone direct me to a 4x8 panel that would look good? Thank you all so much in advance ... I'm stumped on this one!
