These were pretty easy to work with.  We put a few tiny nails in them with the nail gun but mostly used a fast drying adhesive to attach them to the wall so they laid completely flat. I’m super happy about how they look.  It did take a while to get them, our first batch got lost so they had to send another and they came later than expected, but wayfair communicated well with us. Overall, I recommend.  These are the only 106” panels I could find in the market, so if you have 9’ ceilings like us, we just had to cut barely a 12 inch off the top and they fit perfectly!
