What a super idea for our chill&relax section of our new familyroom space! I can and will line the wall with a piece of wood to nail our over read books to! Another idea is garage sale books, hospitals have old books that are usually $1+ for as many as you can grab, or your local Second Hand Store should have a pile of useable ones for cheap!
I would also think you could PAINT the wood and add any of your favorite comfort things readable—magazines, a fallen off from my toddlers old hard cover favs! Stick around there’s plenty more DIY’s to come!
