All of the walls are like this. You cannot see through to the other side (the "slats" are close together, but it is not smooth were the edges meet). I met someone the other day that said the house she grew up in was done the same way. She said the fabric behind the wallpaper is cheesecloth, and that I could redo it the same way or use something called liner (lining?) paper instead of cheesecloth to keep the wallpaper from adhering to the ridges between the wood. She said that would give it a smooth appearance. Any thoughts on this? Please let me know if you have any other ideas, or hear of any other suggestions from your friends.
I really appreciate your help, and I think I'll take your advice on getting a good book on restoration!
